seam agate

Discover big personality in a small package with our Natural Seam Agate Small Pear Shape Cabochon from Pedra Gems — a charming 22x17mm gemstone weighing just 13.5 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 6mm dome, this stone rises to a full 6mm — 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: 22x17x5 mm
• Weight: 13.5 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 13.5ct
• 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 6mm dome is the defining feature of this stone — and it makes all the difference. A standard small pear at 22x17 mm with a 6mm 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 22x17mm 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 22x17 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.

✦ 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.

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

Bring refined geometric style to your everyday jewellery with our Natural Seam Agate Small Baguette Cabochon — a charming 29x16mm gemstone weighing just 17.5 carats, cut into a classic rectangular baguette silhouette that delivers sophisticated art deco character in a dainty, lightweight package.

At 29mm this is our smallest baguette cabochon — compact, precise, and beautifully proportioned. The clean straight edges and squared corners of the baguette cut shine even at this petite scale, giving the stone an elegant geometric confidence that round and oval cuts of the same size simply cannot match.

✦ Stone Specifications:
• Shape: Baguette (Rectangle)
• Dimensions: 29x16x4 mm
• Weight: 17.5Carats
• 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 baguette earring pairs — lightweight enough for all-day wear
• Dainty rectangle pendant & bar necklace designs
• Small baguette ring settings
• Minimalist & modern jewellery styles
• Art deco inspired jewellery collections
• Stackable ring designs
• Gothic & alternative small jewellery
• Crystal healing & energy work
• Teen & everyday wearable jewellery

✦ Why This Small Baguette?
At just 29x16mm and 17.5 carats, this is one of the lightest stones across our entire baguette collection — making it an excellent choice for earrings where comfort and wearability through the day are essential.

Two of these stones together would make a beautifully matched pair of geometric baguette studs — a modern, sophisticated alternative to round or oval earring stones. The precise rectangular form reads clearly even at this small scale, making every piece of jewellery made from it look intentional and well-designed.

The near 1.5:1 length-to-width ratio gives this small baguette a classic, balanced rectangular proportion — clearly a rectangle without being overly elongated. The 4mm dome adds just enough height for visual presence and depth without making it too high-profile for comfortable everyday stud earring wear.

The natural Seam Agate banding flows across the compact rectangular face with striking effect — the geometric precision of the baguette cut framing the organic pattern beautifully, creating a piece that is both natural and architectural in character.

Discover timeless natural beauty on a generous scale with our Natural Seam Agate Oval Cabochon from Pedra Gems — a beautifully proportioned 29x19x5mm gemstone weighing 25 carats, combining classic oval form with premium weight and a rich natural Seam Agate character that makes every piece of jewellery made from it uniquely special.

At 29x19mm this oval has a near 1.5:1 length-to-width ratio — one of the most universally flattering and classic oval proportions in jewellery making. This golden oval ratio produces a shape that reads clearly and beautifully as an oval, fitting the widest range of standard oval settings while remaining visually rich and generously sized.

✦ Stone Specifications:
• Shape: Oval
• Dimensions: 29 x 19 x 5 mm
• Weight: 25 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:
• Classic statement oval pendant & necklace designs
• Oval bezel ring settings — a commanding ring centrepiece
• Wire wrapping & bezel settings
• Bridal & occasion jewellery making
• Boho & artisan jewellery collections
• Everyday statement pendant
• Crystal healing & grounding energy work

✦ Why This Oval?
The 29x19mm proportions place this stone firmly in the large oval category — noticeably bigger than our standard mid-size ovals yet beautifully proportioned for both pendant and ring settings. At 29mm long it creates excellent visual length on the neckline as a pendant, while the 19mm width ensures the stone has generous face area displaying the full natural banding of the Seam Agate.

The near 1.5:1 ratio is widely regarded as the sweet spot for oval cabochons — long enough to read as distinctly oval rather than round, wide enough to feel rich and substantial rather than narrow. This is the oval proportion that suits the most buyer preferences and fits the widest range of standard settings.

At 25 carats this is a premium stone with genuine weight. Heavier than our 20ct ovals and lighter than our large collector pieces, this stone sits in the ideal range for buyers who want a genuinely substantial natural gemstone for a statement jewellery piece without moving into showpiece territory.

The 5mm dome adds excellent depth and warm light play across the polished natural agate surface — a classic dome height that gives this oval beautiful visual presence and a satisfying tactile quality in the hand.

Express natural beauty and heartfelt elegance with our Natural Seam Agate Heart Shape Cabochon from Pedra Gems — a beautifully proportioned 19x21x5mm gemstone weighing 15 carats, cut into a deep, upright heart silhouette that radiates warmth, romance and natural character.

At 19x21mm this heart is 2mm taller than wide — a proportion that produces one of the most naturally satisfying and recognisable heart silhouettes in the Pedra Gems collection. The lobes are full and rounded at the top, flowing gracefully downward to a strong, decisive central point that gives the heart its most classic and timeless form.

✦ Stone Specifications:
• Shape: Heart
• Dimensions: 19 x 21 x 5 mm
• Weight: 15 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:
• Classic heart pendant & necklace designs
• Wire wrapping & heart bezel settings
• Statement heart ring centrepiece
• Valentine's Day & anniversary jewellery
• Crystal healing & heart chakra work
• Meaningful romantic gift for gemstone lovers
• Bridal & occasion jewellery making
• Everyday wearable heart pendant

✦ Why This Heart?
The 19x21mm 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 15 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 19×21mm stone is a classic mid-size upright heart — larger and more substantial than our small hearts (13×14mm, 15×16mm) yet more intimate and wearable than our large statement hearts (24×25mm, 26×29mm).

✦ 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.

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 22x17mm gemstone weighing 15 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 22x17mm tumble, offering a substantial organic canvas of natural Seam Agate banding across a generous 22x17mm 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: 22x17x5 mm
• Weight: 15 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 22x17xmm this tumble cabochon is nearly double the face area of our compact 22x17mm 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 15 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.

✦ 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.

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 38x19xmm gemstone weighing a full 25 carats. This is the largest, heaviest, and most magnificent stone we offer — a once-in-a-collection natural treasure of extraordinary scale and beauty.

At 38x19mm 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 25 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: 38x19x4 mm
• Weight: 25 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 38mm it is larger than a standard US quarter dollar (19mm) 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 25 carats this is almost four times the weight of our standard 25ct 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 19mm 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 — 25 carats, 38x19mm, 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.

✦ About Seam Agate:

Introducing one of the most visually dramatic stones in the Pedra Gems collection — our Natural Seam Agate Shield Cabochon, a breathtaking 31x14x4mm gemstone weighing 13.5 carats, combining a rare shield silhouette with an extraordinary explosion of vivid red, orange, yellow and brown natural banding.

This stone stops you in your tracks. The fiery interplay of deep crimson red, warm burnt orange, golden yellow and rich earthy brown — punctuated by mysterious silver-grey areas — creates a natural composition of rare intensity and beauty. No two stones in the world carry this exact combination of colour, pattern, and form.

✦ Stone Specifications:
• Shape: Shield (Kite Cut)
• Dimensions: 31x14x4  mm
• Weight: 13.5 Carats
• Stone Type: Natural Seam Agate
• Colour: Vivid red, orange, yellow, brown & silver-grey natural banding
• 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: This is a one-of-a-kind stone — its shield silhouette, colour combination and banding pattern are entirely unique and will never be replicated.

✦ About the Shield Shape:
The shield cut — also known as the kite cut — is defined by two straight sides that meet at a sharp upper point, one gently curved side, and a sharp lower point. This asymmetric, angular silhouette is one of the rarest and most dramatic shapes in the cabochon world — bold, directional, and deeply distinctive.

At 38mm tall this is a long, elongated shield with a strong vertical presence. The sharp top point draws the eye upward while the curved lower section flows elegantly into the lower tip — creating a stone with genuine visual tension and movement.

✦ Perfect For:
• Show-stopping statement pendant & necklace designs
• Wire wrapping — the two pointed ends provide strong natural anchor points
• Freeform & artistic jewellery collections
• Boho & fire-inspired jewellery designs
• Electroforming & copper wrap projects
• Solar plexus & root chakra crystal healing
• Collectors of rare shapes & vivid natural colour
• Bespoke commission jewellery centrepiece

✦ The Colour Story:
The red tones in this stone are created by iron oxide inclusions within the agate — the same mineral that colours terracotta, rust, and desert sandstone. The golden yellow and burnt orange layers are rich in chalcedony and iron minerals, creating warm, glowing bands that seem to radiate heat. The silver-grey areas add a beautiful cooling contrast — like storm clouds moving across a desert sunset.

This is a stone that tells a geological story millions of years in the making.

✦ 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.

In crystal healing traditions, the fiery red and orange tones of this stone are associated with the root and sacral chakras — bringing energy, passion, creativity, and grounding strength. The golden yellow tones connect to the solar plexus chakra, amplifying confidence and personal power.

The lobes are deep and rounded at the top, flowing down to a strong, decisive central point that gives the heart its most classic and universally recognised form.

✦ Stone Specifications:
• Shape: Heart
• Dimensions: 21 x 24 x 4 mm
• Weight: 14.5 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 heart pendant & necklace designs
• Wire wrapping & heart bezel settings
• Statement heart ring centrepiece
• Valentine's Day & anniversary jewellery
• Crystal healing & heart chakra work
• Meaningful gift for gemstone lovers
• Bridal & romantic jewellery making
• Bespoke commission jewellery centrepiece

✦ Why This Heart?
The near-square 21x24mm proportions place this stone in the sweet spot of the Pedra Gems heart collection — larger and more substantial than our mid-size hearts (19×19mm, 20×19mm) yet more intimate and refined than our larger statement pieces (24×25mm, 26×29mm).

At 14.5 carats this is a confident, premium-weight stone. Heavy enough to feel truly special in the hand and meaningful as a gift, yet perfectly proportioned for comfortable everyday pendant wear. The 5mm dome adds excellent depth and rich natural light play across the polished surface.

The slightly taller-than-wide proportion — just 1mm of difference — gives this heart its beautifully upright, full character. The lobes curve generously at the top, the sides taper naturally inward, and the central point drops cleanly below — the heart silhouette at its most complete and satisfying.

✦ 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 from Pedra Gems 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.

Order today from Pedra Gems and receive a hand-selected natural gemstone — fully polished, flat-backed, and ready to become the heartfelt centrepiece of your next beautiful creation.

Discover big personality in a small package with our Natural Seam Agate Small Pear Shape Cabochon from Pedra Gems — a charming 24x12x4mm gemstone weighing just 8 carats, cut into a dainty teardrop silhouette with an exceptionally deep 6mm 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 4mm dome, this stone rises to a full 4mm — 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: 24x12x4 mm
• Weight: 8 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 8ct
• 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 6mm dome is the defining feature of this stone — and it makes all the difference. A standard small pear at 24x12mm with a 4mm 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 24x12mm 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 8 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.

✦ 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.

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

Elevate your jewellery designs with our Natural Seam Agate Pear Shape Cabochon — an elegantly proportioned 34x20mm gemstone weighing 27.5 carats, cut into a classic teardrop silhouette that jewellers have loved for centuries.

The pear shape combines the graceful curve of an oval with a tapered point, creating a naturally dynamic stone that draws the eye and hangs beautifully in pendant and drop earring designs. Paired with the rich banded character of natural Seam Agate, this cabochon is as distinctive as it is versatile.

✦ Why Pear Shape?
The pear or teardrop shape is one of the most flattering and popular cabochon cuts for pendant jewellery. At 34x20mm, this stone has an ideal length-to-width ratio — long enough to create elegant drop movement, narrow enough to sit delicately against the neckline.

The pointed tip is perfect for wire wrapping techniques, giving the stone a natural anchor point for wrapping and setting, while the rounded base adds visual balance.

Introducing one of the most visually dramatic stones in the Pedra Gems collection — our Natural Seam Agate Shield Cabochon, a breathtaking 41x13x5mm gemstone weighing 21 carats, combining a rare shield silhouette with an extraordinary explosion of vivid red, orange, yellow and brown natural banding.

This stone stops you in your tracks. The fiery interplay of deep crimson red, warm burnt orange, golden yellow and rich earthy brown — punctuated by mysterious silver-grey areas — creates a natural composition of rare intensity and beauty. No two stones in the world carry this exact combination of colour, pattern, and form.

✦ Stone Specifications:
• Shape: Shield (Kite Cut)
• Dimensions: 41x13x5 mm
• Weight: 21 Carats
• Stone Type: Natural Seam Agate
• Colour: Vivid red, orange, yellow, brown & silver-grey natural banding
• 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: This is a one-of-a-kind stone — its shield silhouette, colour combination and banding pattern are entirely unique and will never be replicated.

✦ About the Shield Shape:
The shield cut — also known as the kite cut — is defined by two straight sides that meet at a sharp upper point, one gently curved side, and a sharp lower point. This asymmetric, angular silhouette is one of the rarest and most dramatic shapes in the cabochon world — bold, directional, and deeply distinctive.

At 38mm tall this is a long, elongated shield with a strong vertical presence. The sharp top point draws the eye upward while the curved lower section flows elegantly into the lower tip — creating a stone with genuine visual tension and movement.

✦ Perfect For:
• Show-stopping statement pendant & necklace designs
• Wire wrapping — the two pointed ends provide strong natural anchor points
• Freeform & artistic jewellery collections
• Boho & fire-inspired jewellery designs
• Electroforming & copper wrap projects
• Solar plexus & root chakra crystal healing
• Collectors of rare shapes & vivid natural colour
• Bespoke commission jewellery centrepiece

✦ The Colour Story:
The red tones in this stone are created by iron oxide inclusions within the agate — the same mineral that colours terracotta, rust, and desert sandstone. The golden yellow and burnt orange layers are rich in chalcedony and iron minerals, creating warm, glowing bands that seem to radiate heat. The silver-grey areas add a beautiful cooling contrast — like storm clouds moving across a desert sunset.

This is a stone that tells a geological story millions of years in the making.

✦ 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.

In crystal healing traditions, the fiery red and orange tones of this stone are associated with the root and sacral chakras — bringing energy, passion, creativity, and grounding strength. The golden yellow tones connect to the solar plexus chakra, amplifying confidence and personal power.
