Discover elegant simplicity with our Natural Seam Agate Pear Shape Cabochon — a graceful 28x16mm gemstone weighing carats, offering a generous elongated teardrop silhouette with an exceptionally low 5mm dome profile
This pear cabochon is distinctive in our collection for its slim, flat character. At just 5mm in height, it sits closer to the skin than any standard cabochon, making it a preferred choice for flush bezel settings, lightweight everyday pendants, resin casting, and any design where a low-profile stone is specifically required.
✦ Stone Specifications:
• Shape: Pear (Teardrop)
• Dimensions: 28x16x5 mm
• Weight: 15.5 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, low dome)
• Finish: High-polish, smooth surface
Please note: As these are natural gemstones, size and weight may vary slightly. Dimensions may differ by ±0.5mm and weight by ±0.5ct from the listed measurements.
✦ Perfect For:
• Flush & low-profile bezel settings
• Lightweight everyday pendant designs
• Resin casting & resin art projects
• Macramé & fibre art focal stones
• Wire wrapping — low dome wire travels cleanly across the surface
• Flat lay jewellery photography props
• Boho & minimalist jewellery styles
• Crystal healing & energy work
✦ Why the Low 5mm Dome?
Most cabochons in this size range carry a 5–6mm dome — this stone at just 5mm is noticeably flatter and lighter. That difference matters for several reasons:
For bezel settings, a lower dome means the bezel walls do not need to be as tall, making setting easier and the finished piece sleeker. For wire wrapping, wire travels more smoothly and evenly across a flatter surface. For everyday wear pendants, less height means less snagging on clothing and a more comfortable wearing experience.
At 27x15x5mm the stone has a bold, elongated teardrop footprint — long enough to make a genuine statement as a pendant centrepiece — while the 5mm dome keeps the overall piece feeling refined and wearable rather than chunky.
✦ About Seam Agate:

Celebrated for its grounding and stabilising energy, Seam Agate is beloved by crystal practitioners and artisan jewellers worldwide. Its warm tones complement sterling silver, gold-filled, and copper wire settings beautifully.

Experience the raw, organic beauty of nature on a grand scale with this Large Natural Seam Agate Tumble Shape Cabochon from Pedra Gems — a generous 19x13mm gemstone weighing 8.5 carats, shaped into a smooth, flowing tumble form that celebrates the natural character of the stone in its fullest expression.
This is our largest tumble cabochon — significantly bigger and more commanding than our compact 19x13mm tumble, offering a substantial organic canvas of natural Seam Agate banding across a generous 19x13mm face. The smooth, continuously flowing curves have no defined edges, no precise angles — just the pure, honest shape that nature and the cutter's hand have created together.
✦ Stone Specifications:
• Shape: Tumble (Organic Rounded)
• Dimensions: 19x13x4 mm
• Weight: 8.5 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, domed top)
• Finish: High-polish, smooth surface
• Please note: As these are natural gemstones, size and weight may vary slightly. Dimensions may differ by ±0.5mm and weight by ±0.5ct from the listed measurements.
• Shape note: Tumble shapes are unique by nature — the organic silhouette of this stone is individual to this piece and will not be replicated in any other.
✦ Perfect For:
• Large statement pendant & showpiece necklace designs
• Wire wrapping — smooth continuous curves wrap beautifully with no sharp edges or corners
• Oversized boho & nature-inspired jewellery designs
• Electroforming & large copper wrap projects
• Focal stone for macramé & fibre art
• Crystal healing & grounding energy work
• Display & collector pieces
• Bespoke commission jewellery centrepiece
✦ Why This Large Tumble?
Size matters here. At 19x13mm this tumble cabochon is nearly double the face area of our compact 19x13mm tumble — a genuinely large, statement-scale stone that commands attention as a pendant centrepiece. The generous organic form means the natural Seam Agate banding flows across a wide, open canvas, displaying its full character without constraint.
The tumble shape at this scale is particularly powerful for wire wrapping. The smooth, continuous curves allow wire to travel freely and naturally around the entire perimeter without a single sharp corner or angle to navigate — producing graceful, organic wrapping lines that complement the natural character of the stone perfectly. The larger the tumble, the more room for the wire artist to work — and at 30x18mm there is ample surface area for truly detailed, intricate wire designs.
At 8.5 carats this is a premium stone with genuine weight and substance — the kind of stone that feels immediately special in the hand. The 5mm dome adds excellent visual depth and warm light play across the polished surface, giving this large tumble a rich, glowing presence that smaller stones simply cannot replicate.

Seam Agate is a natural chalcedony formed within rock seams and fissures, producing its characteristic richly layered banding in warm, earthy tones. No two stones from Pedra Gems share the same pattern, colour, or flow — every cabochon is a completely unique piece of natural art.
The tumble shape is the perfect vessel for Seam Agate's organic banding — both the shape and the pattern speak the same natural language of flowing curves and warm, grounded energy.
Celebrated for its grounding and stabilising energy, Seam Agate is a favourite among crystal practitioners and artisan jewellers worldwide.

Presenting the crown jewel of the Pedra Gems collection — our Natural Seam Agate XL Oval Cabochon, a breathtaking 34x22mm gemstone weighing a full 35.5carats. This is the largest, heaviest, and most magnificent stone we offer — a once-in-a-collection natural treasure of extraordinary scale and beauty.
At 34mm this oval is genuinely large — roughly the size of a large walnut and larger than most standard brooch blanks. The near 1.5:1 length-to-width ratio produces a beautifully balanced, full-bodied oval that displays the natural Seam Agate banding across a canvas of exceptional scale. Every layer, every band, every colour variation is visible in generous, sweeping detail that smaller stones simply cannot reveal.
The 6mm dome rises confidently above the surface, adding extraordinary visual depth and a rich, three-dimensional quality that makes the banding appear to glow from within. At 35.5 carats the stone carries a weight and substance in the hand that immediately communicates premium natural quality to any experienced collector or jeweller.
✦ Stone Specifications:
• Shape: Oval
• Dimensions: 34x22x6 mm
• Weight: 35.5 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, deep domed top)
• Finish: High-polish, smooth surface
• Please note: As these are natural gemstones, size and weight may vary slightly. Dimensions may differ by ±0.5mm and weight by ±0.5ct from the listed measurements.
✦ Perfect For:
• Large statement brooch & pin centrepiece
• Bespoke commission jewellery — ring, cuff, pendant, collar
• Statement cuff bracelet focal stone
• Large wire wrapping & oversized bezel settings
• Electroforming & large copper wrap projects
• Display & museum-quality collector piece
• Crystal healing — the largest healing stone in the Pedra Gems range
• Interior design & decorative gemstone display
• Investment-grade natural gemstone collection
✦ Scale & Presence:
To appreciate the scale of this stone — at 34mm it is larger than a standard US quarter dollar (22mm) in both dimensions. In a brooch setting it would command the full focal point of any outfit. In a wire-wrapped pendant it would be a dramatic, statement piece that draws attention from across a room.
At 35.5 carats this is almost four times the weight of our standard 35.5ct ovals — the sheer mass of natural Seam Agate material in this stone represents exceptional geological quality. Stones of this size and weight with clean, polished surfaces and rich natural banding are rare and increasingly sought after by serious collectors.
The 6mm deep dome adds a spectacular visual dimension — at 34mm wide the dome creates a generous, rounded profile with light play across the polished surface that shifts and changes with every movement and every light source.
✦ Investment & Rarity:
Large natural cabochons of this quality — 35.5 carats, 34x22mm, deep dome, fully polished — are genuinely rare. As natural gemstone rough of this quality becomes increasingly scarce, large premium cabochons like this one are recognised by serious collectors as both beautiful objects and sound natural gemstone investments.

Experience timeless natural beauty with our Natural Seam Agate Round Cabochon — a perfectly circular 5mm gemstone weighing 21carats, offering the most universally versatile shape in jewellery making combined with the rich, earthy character of genuine Seam Agate.
At exactly 23mm, this is a true round cabochon — equal in width and height — making it a perfect fit for standard 23mm round bezel settings, ring mounts, and pendant blanks straight from the box. No custom fitting, no guesswork — just a beautifully natural stone ready to set.
✦ Stone Specifications:
• Shape: Round (Circle)
• Dimensions: 23x23x5 mm (20mm diameter)
• Weight: 21 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, domed top)
• Finish: High-polish, smooth surface
• Please note: As these are natural gemstones, size and weight may vary slightly. Dimensions may differ by ±0.5mm and weight by ±0.5ct from the listed measurements.
✦ Perfect For:
• Round bezel pendant & necklace settings
• 25mm ring bezel settings
• Wire wrapping & round frame settings
• Stud & statement earring designs
• Brooch & pin centrepiece
• Crystal healing & all-purpose energy work
• Beginners & experienced jewellery makers alike
✦ Why Round Shape?
The round cabochon is the most classic and widely used shape in gemstone jewellery — and for good reason. Its perfect symmetry means it works in any orientation, fits the widest range of standard settings available, and suits every jewellery style from minimalist to bohemian to fine jewellery.
At 23mm diameter, this stone is a confident, substantial size — large enough to command attention as a pendant centrepiece or statement ring stone, yet proportionate enough for everyday wear. The 5mm dome gives it excellent visual depth and a satisfying, tactile quality.
At 21 carats, this round cabochon carries impressive weight for its size — a testament to the density and quality of the natural Seam Agate material.
✦ Beginner Friendly:
Round cabochons are the easiest shape to work with for new jewellery makers — standard round bezels are the most widely available and affordable setting type, making this stone an excellent choice for those just starting out in wire wrapping or bezel setting.
✦ About Seam Agate:
Seam Agate is a natural chalcedony formed within rock seams and fissures, producing richly layered banding in warm, earthy tones. No two stones share the same pattern, colour, or flow — every cabochon is a completely unique piece of natural art.
Celebrated for its grounding and stabilising energy, Seam Agate is a favourite among crystal practitioners and artisan jewellers worldwide. Its warm tones complement silver, gold, and copper settings equally well.

Experience the beauty of nature's own geometry with our Natural Seam Agate Freeform Rounded Corner Triangle Cabochon — a captivating 31x15x5mm gemstone weighing 18 carats, shaped into an elongated triangular silhouette where every corner flows into a soft, organic curve rather than a sharp point.
This stone occupies a wonderful creative space between geometric and organic. Its three-sided triangular form gives it strong directional energy and visual structure — but the rounded corners soften every angle into a gentle, flowing curve that feels warm, natural, and deeply wearable. It is a triangle that has been touched by nature.
✦ Stone Specifications:
• Shape: Freeform (Rounded Corner Triangle)
• Dimensions: 31 x 15 x 5 mm
• Weight: 18 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, domed top)
• Finish: High-polish, smooth surface
• Please note: As these are natural gemstones, size and weight may vary slightly. Dimensions may differ by ±0.5mm and weight by ±0.5ct from the listed measurements.
• Shape note: Freeform stones are unique by nature — the exact curvature of the corners, banding pattern, and silhouette of this stone are individual to this piece and will not be replicated in any other.
✦ Perfect For:
• Long drop pendant & statement necklace designs
• Wire wrapping — rounded corners wrap smoothly with no sharp pressure points
• Boho & nature-inspired jewellery collections
• Electroforming & copper wrap projects
• Focal stone for macramé & fibre art
• Modern geometric jewellery with an organic twist
• Crystal healing & energy work
• Collectors of rare organic geometric shapes
✦ Why This Rounded Corner Triangle?
The 31x15mm proportions give this stone a dramatically elongated triangular form — nearly 2.2:1 length-to-width ratio — making it one of your most slender and directional triangle shapes. Wide across the top with a gently tapering base, it creates a strong sense of downward movement ideal for long drop pendants that draw the eye elegantly down the neckline.
The key distinction from your sharp-cornered triangles is the rounded corners. Where sharp corners create angular, geometric tension, rounded corners soften that energy — creating a shape that feels simultaneously structured and organic. This makes the stone more versatile across jewellery styles, equally at home in a boho wire-wrapped pendant and a modern minimalist setting.
The rounded corners are also a practical advantage for wire wrappers. Unlike sharp-cornered triangles that require tight corner wraps, the gentle curves allow wire to flow continuously and smoothly around the entire perimeter — producing naturally graceful, fluid wrapping lines with no awkward angles to navigate.
At 30mm long this is one of your longest triangle-family stones — a bold, dramatic drop pendant stone with serious visual presence. The 5mm dome adds excellent depth and rich light play, making the natural Seam Agate banding glow beautifully across the elongated face.
✦ About Seam Agate:
Seam Agate is a natural chalcedony formed within rock seams and fissures, producing its characteristic richly layered banding in warm, earthy tones. No two stones share the same pattern, colour, or flow — every cabochon is a completely unique piece of natural art.
The flowing organic banding of Seam Agate pairs beautifully with the softly rounded triangular form — both sharing the same language of gentle curves and natural movement.
Celebrated for its grounding and stabilising energy, Seam Agate is beloved by crystal practitioners and artisan jewellers worldwide.
Order today and receive this exact hand-selected gemstone — its rounded corners, elongated silhouette, and natural banding are entirely one of a kind and will never be repeated.
Discover elegant simplicity with our Natural Seam Agate Pear Shape Cabochon — a graceful 27x15x5mm gemstone weighing carats, offering a generous elongated teardrop silhouette with an exceptionally low 5mm dome profile
This pear cabochon is distinctive in our collection for its slim, flat character. At just 3mm in height, it sits closer to the skin than any standard cabochon, making it a preferred choice for flush bezel settings, lightweight everyday pendants, resin casting, and any design where a low-profile stone is specifically required.
✦ Stone Specifications:
• Shape: Pear (Teardrop)
• Dimensions: 27x15x5 mm
• Weight: 14.5 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, low dome)
• Finish: High-polish, smooth surface
Please note: As these are natural gemstones, size and weight may vary slightly. Dimensions may differ by ±0.5mm and weight by ±0.5ct from the listed measurements.
✦ Perfect For:
• Flush & low-profile bezel settings
• Lightweight everyday pendant designs
• Resin casting & resin art projects
• Macramé & fibre art focal stones
• Wire wrapping — low dome wire travels cleanly across the surface
• Flat lay jewellery photography props
• Boho & minimalist jewellery styles
• Crystal healing & energy work
✦ Why the Low 5mm Dome?
Most cabochons in this size range carry a 5–6mm dome — this stone at just 5mm is noticeably flatter and lighter. That difference matters for several reasons:
For bezel settings, a lower dome means the bezel walls do not need to be as tall, making setting easier and the finished piece sleeker. For wire wrapping, wire travels more smoothly and evenly across a flatter surface. For everyday wear pendants, less height means less snagging on clothing and a more comfortable wearing experience.
At 27x15x5mm the stone has a bold, elongated teardrop footprint — long enough to make a genuine statement as a pendant centrepiece — while the 5mm dome keeps the overall piece feeling refined and wearable rather than chunky.

Bring bold geometric character to your everyday jewellery with our Natural Seam Agate Small Triangular Cabochon — a charming 25x22x6mm gemstone weighing just 27.5 carats, cut into a compact triangular silhouette that delivers modern, geometric style in a dainty, lightweight package.
At 25x22mm this is a small, near-equilateral triangle — compact, balanced, and beautifully proportioned. The natural Seam Agate banding flows across the three-sided face with striking effect, making this petite stone far more visually interesting than a plain round or oval of the same size.
✦ Stone Specifications:
• Shape: Triangular
• Dimensions: 25x22x6 mm
• Weight: 27.5 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, domed top)
• Finish: High-polish, smooth surface
• Please note: As these are natural gemstones, size and weight may vary slightly. Dimensions may differ by ±0.5mm and weight by ±0.5ct from the listed measurements.
✦ Perfect For:
• Geometric stud & post earring designs
• Matching triangle earring pairs
• Dainty triangle pendant & charm necklaces
• Small triangle ring settings
• Modern & minimalist jewellery styles
• Gothic & alternative small jewellery
• Crystal healing & energy work
• Children's & teen geometric jewellery
• Stacking rings & layering jewellery
✦ Why This Small Triangle?
At just 25x22mm and 27.5 carats, this is one of the lightest stones in our collection — making it an excellent choice for earrings where comfort and wearability are essential. Two of these stones together would make a beautifully matched pair of geometric triangle studs — lightweight enough for all-day wear, distinctive enough to draw compliments.
The near-equilateral proportions (25mm wide x 22mm tall) give this triangle a compact, balanced silhouette — not elongated or skewed, but a clean, confident three-sided form that sits neatly in standard triangular bezel settings.
The 6mm dome gives the stone just enough height for visual presence and natural depth without making it too high-profile for everyday stud earring wear.
The contrast between the organic, flowing natural agate banding and the sharp geometric triangle silhouette creates a uniquely compelling visual — earthy and bold, natural and designed, all in one small but powerful stone.

Discover big personality in a small package with our Natural Seam Agate Small Pear Shape Cabochon from Pedra Gems — a charming 25x16mm gemstone weighing just 14.5 carats, cut into a dainty teardrop silhouette with an exceptionally deep 5mm dome that gives this petite stone a visual richness and presence far beyond its compact size.
This is one of the most unique small stones in the Pedra Gems collection. While most small pear cabochons carry a low 5mm dome, this stone rises to a full 5mm — creating a rounded, deeply three-dimensional profile that catches light beautifully from every angle. The result is a small stone that feels bold, confident and richly natural in any jewellery setting.
✦ Stone Specifications:
• Shape: Pear (Teardrop)
• Dimensions: 25x16x4 mm
• Weight: 14.5 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, deep domed top)
• Finish: High-polish, smooth surface
• Please note: As these are natural gemstones, size and weight may vary slightly. Dimensions may differ by ±0.5mm and weight by ±0.5ct from the listed measurements.
✦ Perfect For:
• Dainty drop pendant & charm necklace designs
• Dangle & drop earring settings — lightweight at 14.5ct
• Matching teardrop earring pairs
• Small pear ring settings
• Bridal & occasion jewellery making
• Boho & minimalist jewellery styles
• Wire wrapping — pointed tip provides natural anchor point
• Crystal healing & energy work
✦ Why This Small Pear Stands Out:
The 4mm dome is the defining feature of this stone — and it makes all the difference. A standard small pear at 25x16x4 mm with a 4mm dome reads as flat and modest. This stone at 4mm dome reads as bold and richly three-dimensional, with a generous rounded profile that catches light beautifully from every angle and looks substantially more impressive than its dimensions alone would suggest.
At 25x16mm the stone has a near 1.55:1 length-to-width ratio — a classic, balanced teardrop proportion that reads clearly and beautifully as a pear even at this small scale. The rounded top curves confidently before tapering to an elegant pointed tip below — a classic teardrop form in miniature.
At just 14.5 carats this is lightweight enough for comfortable all-day earring wear — two of these stones together would make a beautifully matched pair of deep-dome teardrop earrings with a presence and richness that flat stones at the same size simply cannot match. The deep dome adds satisfying visual weight without adding physical weight.

Bring timeless elegance to your jewellery designs with our Natural Seam Agate Marquise Cabochon — a beautifully elongated 25x10mm gemstone weighing 4.5 carats, cut into the distinctive marquise silhouette beloved by fine jewellery makers and artisan designers alike.
The marquise shape — also known as the navette or "little boat" cut — features an elongated elliptical body tapering to a sharp point at both ends. This iconic double-pointed silhouette is one of the most refined and dramatic shapes in gemstone jewellery, prized for its ability to elongate the finger, lengthen the neckline, and add a sense of movement and grace to any setting.
✦ Stone Specifications:
• Shape: Marquise (Navette)
• Dimensions: 25x10x2 mm
• Weight: 4.5 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, domed top)
• Finish: High-polish, smooth surface
• Please note: As these are natural gemstones, size and weight may vary slightly. Dimensions may differ by ±0.5mm and weight by ±0.5ct from the listed measurements.
✦ Perfect For:
• Statement pendant & drop necklace designs
• Marquise ring centrepiece settings
• Wire wrapping — both pointed ends provide natural anchor points
• Art deco & vintage-inspired jewellery
• Elongated bezel & navette setting designs
• Crystal healing & energy work
• Collectors of elegant gemstone shapes
✦ Why Marquise Shape?
The marquise is one of the most flattering shapes in all of jewellery making. Its 26x11mm proportions produce a length-to-width ratio of nearly 2.4:1 — a dramatic, elongated form that creates a strong visual line in any design.
When set as a ring stone, the marquise shape visually elongates the finger — a well-known effect that has made it a perennial favourite in engagement and statement ring design. As a pendant, the double-pointed form creates natural movement and a dynamic, directional energy that oval and round stones simply cannot match.
The two pointed tips are a practical advantage for wire wrappers — each tip provides a natural anchor point for wrapping, creating a symmetrical, balanced design with structural integrity at both ends.
At 25x10 alternative jewellery stone. 4.5 carats and 2mm dome, this is a substantial and visually commanding stone — full of rich natural Seam Agate banding across its generous surface area.

This is one of the most unique small stones in the Pedra Gems collection. While most small pear cabochons carry a low 5mm dome, this stone rises to a full 5mm — creating a rounded, deeply three-dimensional profile that catches light beautifully from every angle. The result is a small stone that feels bold, confident and richly natural in any jewellery setting.

✦ Why This Small Pear Stands Out:
The 5mm dome is the defining feature of this stone — and it makes all the difference. A standard small pear at 24x14x6 mm with a 5mm dome reads as flat and modest. This stone at 6mm dome reads as bold and richly three-dimensional, with a generous rounded profile that catches light beautifully from every angle and looks substantially more impressive than its dimensions alone would suggest.
At 24x14mm the stone has a near 1.55:1 length-to-width ratio — a classic, balanced teardrop proportion that reads clearly and beautifully as a pear even at this small scale. The rounded top curves confidently before tapering to an elegant pointed tip below — a classic teardrop form in miniature.

✦ Why This Small Pear Stands Out:
The 5mm dome is the defining feature of this stone — and it makes all the difference. A standard small pear at 27x16 mm with a 5mm dome reads as flat and modest. This stone at 5mm dome reads as bold and richly three-dimensional, with a generous rounded profile that catches light beautifully from every angle and looks substantially more impressive than its dimensions alone would suggest.
At 32x20mm the stone has a near 1.55:1 length-to-width ratio — a classic, balanced teardrop proportion that reads clearly and beautifully as a pear even at this small scale. The rounded top curves confidently before tapering to an elegant pointed tip below — a classic teardrop form in miniature.
At just 19.5 carats this is lightweight enough for comfortable all-day earring wear — two of these stones together would make a beautifully matched pair of deep-dome teardrop earrings with a presence and richness that flat stones at the same size simply cannot match.

✦ Size Reference:
Not sure how big this stone is? At 31x18mm it is slightly larger than a US quarter dollar in length — a bold, generous size with real presence on the neckline or finger.
✦ Why Coffin Shape?
The coffin or casket cabochon is one of the most sought-after alternative shapes in the gemstone world. Its angular lines contrast beautifully with the organic, flowing bands of natural agate — creating a piece that feels both raw and refined at once.
At 30 carats with a 5mm dome, this is a substantial stone with impressive depth and excellent light play across its polished surface.
✦ About Seam Agate:
Seam Agate is a natural chalcedony formed within rock seams and fissures, producing its characteristic richly layered banding patterns. Each stone is entirely unique in colour, flow, and character — no two cabochons are ever the same.
In crystal healing traditions, Agate is associated with protection, grounding, and inner strength — qualities that align naturally with the bold symbolism of the coffin shape.

✦ Why This Heart?
The 29x27mm proportions give this heart a naturally upright, deep character — the extra 2mm of height over width creates full, generous lobes at the top and a confident downward point that is deeply satisfying in both pendant and ring settings.
At 27.5 carats this stone sits in the ideal mid-size range — substantial enough to feel genuinely meaningful and premium as a gift or pendant centrepiece, yet light and compact enough for comfortable everyday wear. It is the sweet spot between the dainty small hearts and the bold large statement pieces in the Pedra Gems collection.
The 5mm dome adds excellent depth and warm light play across the polished natural agate surface — a classic dome height that gives this heart beautiful visual presence from every angle.
✦ Your Pedra Gems Heart Collection:
With over 10 heart listings, Pedra Gems offers one of the most comprehensive natural agate heart ranges available. This 29x27mm stone is a classic mid-size upright heart — larger and more substantial than our small hearts (29x27mm) yet more intimate and wearable than our large statement hearts (29x27)
✦ About Seam Agate:
Seam Agate is a natural chalcedony formed within rock seams and fissures, producing its characteristic richly layered banding in warm, earthy tones. No two stones from Pedra Gems share the same pattern, colour, or flow — every cabochon is a completely unique piece of natural art.
In crystal healing traditions, the heart shape combined with Agate's grounding energy makes this a powerful stone for heart chakra work — promoting love, compassion, emotional balance and inner strength.

Presenting the crown jewel of the Pedra Gems collection — our Natural Seam Agate XL Oval Cabochon, a breathtaking 30x15xmm gemstone weighing a full 19.5carats. This is the largest, heaviest, and most magnificent stone we offer — a once-in-a-collection natural treasure of extraordinary scale and beauty.
At 30x15mm this oval is genuinely large — roughly the size of a large walnut and larger than most standard brooch blanks. The near 1.5:1 length-to-width ratio produces a beautifully balanced, full-bodied oval that displays the natural Seam Agate banding across a canvas of exceptional scale. Every layer, every band, every colour variation is visible in generous, sweeping detail that smaller stones simply cannot reveal.
The 4mm dome rises confidently above the surface, adding extraordinary visual depth and a rich, three-dimensional quality that makes the banding appear to glow from within. At 19.5 carats the stone carries a weight and substance in the hand that immediately communicates premium natural quality to any experienced collector or jeweller.
✦ Stone Specifications:
• Shape: Oval
• Dimensions: 30x15x5 mm
• Weight: 19.5 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, deep domed top)
• Finish: High-polish, smooth surface
• Please note: As these are natural gemstones, size and weight may vary slightly. Dimensions may differ by ±0.5mm and weight by ±0.5ct from the listed measurements.
✦ Perfect For:
• Large statement brooch & pin centrepiece
• Bespoke commission jewellery — ring, cuff, pendant, collar
• Statement cuff bracelet focal stone
• Large wire wrapping & oversized bezel settings
• Electroforming & large copper wrap projects
• Display & museum-quality collector piece
• Crystal healing — the largest healing stone in the Pedra Gems range
• Interior design & decorative gemstone display
• Investment-grade natural gemstone collection
✦ Scale & Presence:
To appreciate the scale of this stone — at 30mm it is larger than a standard US quarter dollar (15mm) in both dimensions. In a brooch setting it would command the full focal point of any outfit. In a wire-wrapped pendant it would be a dramatic, statement piece that draws attention from across a room.
At 19.5 carats this is almost four times the weight of our standard 19.5ct ovals — the sheer mass of natural Seam Agate material in this stone represents exceptional geological quality. Stones of this size and weight with clean, polished surfaces and rich natural banding are rare and increasingly sought after by serious collectors.
The 4mm deep dome adds a spectacular visual dimension — at 15mm wide the dome creates a generous, rounded profile with light play across the polished surface that shifts and changes with every movement and every light source.
✦ Investment & Rarity:
Large natural cabochons of this quality — 19.5 carats, 30x15mm, deep dome, fully polished — are genuinely rare. As natural gemstone rough of this quality becomes increasingly scarce, large premium cabochons like this one are recognised by serious collectors as both beautiful objects and sound natural gemstone investments.
