seam agate

Discover a truly rare and organic gemstone form with our Natural Seam Agate Free Form Rounded Triangle Cabochon — a striking 24x18x6mm stone weighing 19carats, shaped into a softly triangular silhouette where every edge and corner is naturally rounded and smooth rather than sharp or angular.

This is not a precision geometric triangle. It is a free form cabochon that nature and the cutter's hand have shaped into a gentle, organic triangle-like form — wide at one end, tapering toward the other, with all edges flowing in soft curves rather than hard angles. The result is a stone that feels simultaneously architectural and natural — grounded and earthy, yet boldly shaped.

✦ Stone Specifications:
• Shape: Free Form (Rounded Triangle — organic soft-edged silhouette)
• Dimensions: 24 x 18 x 6 mm
• Weight: 19 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: Free form stones are unique by nature — the rounded triangular silhouette, edge curvature, and banding pattern of this stone are individual to this piece and will not be replicated in any other.

✦ Perfect For:
• Statement pendant & long drop necklace designs
• Wire wrapping — soft rounded edges wrap beautifully and comfortably
• Boho & nature-inspired jewellery collections
• Electroforming & copper wrap projects
• Focal stone for macramé & fibre art
• Crystal healing & energy work
• Collectors of rare & unusual organic gemstone shapes

✦ Why Rounded Triangle?
The rounded triangle is one of the most visually compelling shapes in the freeform cabochon world. Sharp-cornered triangles can look harsh and geometric — but when all edges are softly rounded, the stone takes on a warm, organic character that is both distinctive and deeply wearable.

At 36mm long and just 16mm wide, this is a dramatically elongated stone — one of the longest in our collection. Its slender footprint makes it ideal for long drop pendants that create vertical movement on the neckline. The low 6mm dome keeps the overall piece sleek and elegant despite the generous length.

The soft rounded edges are also a practical advantage for wire wrapping — smooth curves allow wire to travel cleanly along the perimeter without catching or creating uncomfortable pressure points against the skin.

✦ 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 character — and with a free form cut, not even the shape is ever repeated.

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

Order today and receive this exact hand-selected gemstone — its rounded triangular form, banding, and character are entirely one of a kind and will never be repeated.

Make a bold statement with our Large Natural Seam Agate Heart Shape Cabochon — a striking 24x23x5mm gemstone weighing 22.5 carats, designed for jewellery makers who love to create pieces that truly stand out.

This oversized heart cabochon is one of our largest cuts, offering an impressive canvas of natural Seam Agate banding. Its generous proportions make it a showstopping centrepiece for pendants, statement rings, and bespoke wire-wrapped designs.

✦ Stone Specifications:

At 24x23mm and 22.5 carats, this is a large, impressive heart cabochon that commands attention.

The 5mm dome adds beautiful depth and a rich tactile quality that smaller stones simply cannot match.

✦ About Seam Agate:
Seam Agate is a natural chalcedony formed within the seams and fissures of host rock, producing its distinctive flowing, layered banding. Each stone carries its own unique pattern of colour and line — no two are ever alike.

Discover timeless natural elegance with our Natural Seam Agate Oval Cabochon — a beautifully proportioned 28x18x4mm gemstone weighing 17 carats, combining classic oval form with a sleek low-profile dome that makes it one of the most versatile and wearable stones in our collection.

At 28x18mm this oval has a near 1.6:1 length-to-width ratio — widely regarded among jewellers as one of the most flattering and universally appealing oval proportions available. Not too elongated, not too wide, this stone sits in the sweet spot that works beautifully in every setting style from classic fine jewellery to boho wire wrapping.

✦ Stone Specifications:
• Shape: Oval
• Dimensions: 28 x 18 x 4 mm
• Weight: 17 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:
• Classic oval pendant & necklace designs
• Oval bezel ring settings
• Wire wrapping & bezel settings
• Everyday wearable pendant designs
• Flush & low-profile bezel settings
• Bridal & occasion jewellery making
• Boho & minimalist jewellery styles
• Crystal healing & grounding energy work

✦ Why This Oval?
Two features make this stone stand out — its classic proportions and its low 4mm dome.

The 28x18mm proportions produce a near 1.6:1 ratio — the golden ratio of oval cabochons. This proportion is the most universally flattering for oval stones because it creates a shape that reads clearly as an oval without looking elongated or stubby. It suits standard oval bezel settings, ring mounts, and pendant blanks that buyers already have in their collection.

The 4mm dome is lower than most cabochons of this size, which carries three practical advantages. For everyday pendant wear, a lower dome sits closer to the skin and catches on clothing less. For bezel settings, lower dome walls are needed making setting easier and the finished piece sleeker. For wire wrapping, wire travels more smoothly and evenly across a flatter surface producing cleaner wrapping lines.

At 17 carats this is a well-weighted stone — substantial enough to feel premium as a pendant centrepiece while remaining perfectly comfortable for daily wear. A reliable, beautiful, endlessly versatile natural gemstone.

✦ About Seam Agate:

Embrace pure natural beauty with our Natural Seam Agate Tumble Shape Cabochon — a wonderfully organic 21x15x5mm gemstone weighing 11.5 carats, shaped into a smooth, softly rounded tumble form that echoes the natural character of a polished river stone.

Unlike geometric cuts such as oval, round, or pear, the tumble shape has no defined edges, precise angles, or symmetrical outline. Instead it flows freely — curves shifting gently into one another, creating an entirely natural, organic silhouette that is as individual as the banding pattern within the stone itself. It is nature at its most honest and beautiful.

✦ Stone Specifications:
• Shape: Tumble (Organic Rounded)
• Dimensions: 21 x 15 x 5 mm
• Weight: 11.5 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:
• Boho & nature-inspired pendant designs
• Wire wrapping — smooth curves wrap beautifully with no sharp edges
• Organic & freeform jewellery collections
• Electroforming & copper wrap projects
• Crystal healing & energy work — tactile, comfortable to hold
• Macramé & fibre art focal stones
• Meditation & pocket stone display
• Collectors of natural organic gemstone forms

✦ Why Tumble Shape?
The tumble shape is one of the most beloved forms among crystal healers, boho jewellery makers, and natural stone collectors. Its smooth, rounded, flowing silhouette feels instinctively natural in the hand — warm, comfortable, and deeply organic.

For wire wrappers, the tumble shape is a joy to work with. The absence of sharp corners or defined edges means wire flows smoothly and continuously around the perimeter without catching or requiring tight corner wraps. The result is naturally graceful, fluid wire work that complements the organic character of the stone perfectly.

At 21x15mm this tumble cabochon is a versatile mid-size — large enough to make a clear pendant centrepiece while compact enough for everyday wearable jewellery. The 5mm dome gives the stone excellent depth and a satisfying, rounded tactile quality.

At 11.5 carats this is a well-weighted stone with real substance — the weight and smooth form together create a grounded, satisfying quality that crystal healing practitioners particularly appreciate.

✦ 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 tumble shape is the perfect vessel for Seam Agate's organic banding — both the shape and the pattern speak the same natural language, creating a stone that feels completely at home in the world and deeply connected to the earth.

Celebrated for its grounding and stabilising energy, Seam Agate is a favourite among crystal practitioners and artisan jewellers worldwide.

Express natural beauty and heartfelt elegance with our Natural Seam Agate Heart Shape Cabochon — a beautifully proportioned 24x25x5mm gemstone weighing 23 carats, cut into a classic upright heart silhouette that combines generous size with timeless romantic form.

At 24x25mm, this heart is slightly taller than it is wide — a proportion that produces one of the most recognisable and classic heart silhouettes in jewellery. The deeper-than-wide form gives the lobes a full, rounded curvature at the top and draws down to a strong, decisive central point — a heart shape that reads clearly, boldly, and beautifully from every distance.

✦ Stone Specifications:
• Shape: Heart
• Dimensions: 24 x 25 x 5 mm
• Weight: 23 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 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

✦ Why This Heart?
The 24x25mm proportions of this cabochon sit in a sweet spot — large enough to make a genuine statement as a pendant centrepiece, yet perfectly shaped for settings that require a classic, upright heart silhouette.

The taller-than-wide proportion is key. Hearts that are wider than tall can look flat or splayed — hearts that are taller than wide, like this one, have a deep, full-bodied curvature and a strong downward point that gives the silhouette its most recognisable and satisfying form. This is the heart shape that most people picture when they close their eyes and imagine a heart.

At 23 carats this is a substantial mid-to-large stone — heavy enough to feel premium and meaningful in the hand, wearable enough for everyday pendants and occasional statement pieces alike.

The 5mm dome adds excellent depth and rich light play across the polished surface — a full, rounded dome that catches light beautifully and gives the stone a warm, glowing presence.

Bring timeless architectural elegance to your jewellery designs with our Natural Seam Agate Baguette Cabochon — a striking 27x15x5mm gemstone weighing 23 carats, cut into the classic elongated rectangular baguette silhouette that has been a cornerstone of fine and art deco jewellery design for over a century.

The baguette shape — named after the French bread for its long rectangular form — features straight parallel sides, squared corners, and a clean, precise outline that is simultaneously bold and refined. When paired with the organic, flowing banding of natural Seam Agate, the sharp geometric lines of the baguette create a beautiful and compelling contrast between the natural and the architectural.

✦ Stone Specifications:
• Shape: Baguette (Rectangle)
• Dimensions: 27 x 15 x 5 mm
• Weight: 23 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, domed top)

• Modern architectural jewellery collections
• Wire wrapping & rectangular bezel settings
• Statement bar pendant & necklace designs
• Bold ring centrepiece settings
• Brooch & pin focal stone
• Crystal healing & grounding energy work
• Collectors of elegant geometric gemstone shapes

✦ Why Baguette Shape?
The baguette is one of the most sophisticated and timeless shapes in all of gemstone jewellery. Its straight lines and squared corners create a strong architectural presence — clean, deliberate, and unmistakably intentional. No other shape communicates refined elegance and geometric confidence quite like a baguette.

At 27x15mm the stone has a near 1.8:1 length-to-width ratio — a classic elongated baguette proportion that reads as a bold horizontal or vertical bar in any setting. This makes it exceptionally versatile — worn vertically as a drop pendant it creates a strong downward line; set horizontally as a bar pendant or ring stone it creates a wide, confident statement.

The squared corners and straight sides of this shape work beautifully in bezel settings — four clean straight walls make for a precise, professional-looking set stone. For wire wrappers, the flat straight edges provide a natural guide for wire, creating clean geometric wrapping lines that complement the architectural character of the shape.

At 23 carats with a 5mm dome, this is a substantial, premium-quality stone — full of character, rich in natural banding, and ready to anchor a truly exceptional jewellery piece.

✦ 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 visual tension between the free-flowing organic banding of Seam Agate and the crisp, architectural baguette silhouette makes this stone a genuinely compelling jewellery design element — natural and geometric, earthy and refined, all in one outstanding stone.

Celebrated for its grounding and stabilising energy, Seam Agate is beloved by crystal practitioners and artisan jewellers worldwide.

Discover one of the fullest, most generously proportioned teardrop stones in our collection — our Natural Seam Agate Pear Shape Cabochon, a beautifully rounded 23x18x5mm gemstone weighing 15.5 carats, cut into a wide, plump teardrop silhouette that showcases the natural beauty of Seam Agate across an exceptional face area.

At 23x18mm, this pear has one of the lowest length-to-width ratios in our pear range — a near 1.3:1 proportion that creates a wide, rounded, full-bodied teardrop. This is not a slender or elongated pear — it is a generous, rounded drop shape that sits wide and confident on the neckline, displaying the maximum possible face area of natural agate banding.

✦ Stone Specifications:
• Shape: Pear (Teardrop)
• Dimensions: 23 x 18 x 5 mm
• Weight: 15.5 Carats
• Stone Type: Natural Seam Agate

• Wire wrapping — generous surface area for detailed wrapping
• Pear shaped statement ring centrepiece
• Bezel & prong pendant settings
• Bridal & occasion jewellery making
• Boho & artisan jewellery collections
• Crystal healing & energy work

✦ Why This Wide Pear?
The 23x18mm proportions place this stone in a unique position across our pear range. With a near 1.3:1 length-to-width ratio, this is one of the widest, fullest-bodied pear cuts we offer — sitting beautifully between a pear and a rounded oval in character.

That generous width means more natural agate banding is visible across the face of the stone than any of our slender pear cuts. For jewellers who want a pear shape that showcases the stone's natural pattern at maximum impact — this is the one.

The wide rounded top and full body also mean there is ample surface area for detailed wire wrapping work, making this an excellent choice for jewellers who love intricate wire designs that require room to work across the stone face.

The 5mm dome adds excellent depth and rich light play across the polished surface, giving this stone a warm, full presence that catches the eye naturally and holds attention.

At 15.5 carats this is a well-weighted stone — substantial enough to command presence as a pendant centrepiece while remaining comfortable for everyday wear.

✦ Why This Stone Is Exceptional:
At 35 carats and 26x29mm, this heart cabochon is in a class of its own. To put the size in perspective — at 29mm tall this stone is roughly the size of a large coin, making it a bold, unmissable centrepiece in any jewellery design or display collection.

The taller-than-wide proportions give this heart a deep, upright silhouette — an elongated heart form with strong curves at the lobes and a decisive downward point. This silhouette is particularly dramatic when worn as a large drop pendant, the point hanging below and the full face of the stone displaying its natural banding in all its glory.

The 6mm dome — matching our other deep-dome hearts — rises richly above the surface, adding extraordinary visual depth and a three-dimensional quality rarely seen in agate cabochons of this size. Light plays across the polished dome from every angle.

35 carats in natural Seam Agate is a substantial weight. This is a stone made for someone who appreciates quality, scale, and the raw, unrepeatable beauty of natural gemstones.

✦ 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.

Experience the rare magic of a glowing natural gemstone with our Natural Seam Agate Oval Cabochon — a captivating 22x13x5mm stone weighing 13.5 carats, featuring a beautiful partial translucency that allows natural light to pass through and glow warmly from within.

Hold this stone to the light and watch it come alive. The translucent section glows with a soft, warm inner light — a completely natural phenomenon that occurs where silica-rich layers within the agate thin and clear, creating a living interplay of light and shadow across the stone's surface. This is not a common feature in Seam Agate and makes this stone truly one of a kind.

✦ Stone Specifications:
• Shape: Oval
• Dimensions: 22 x 13 x 5 mm
• Weight: 13.5 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, domed top)
• Finish: High-polish, smooth surface
• Special Feature: Partially translucent — natural light passes through
• 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.
• Translucency note: The glowing translucent area is a natural characteristic unique to this individual stone and will not be replicated in any other piece.

✦ Perfect For:
• Wire wrapping — translucent area glows beautifully when pendant is worn
• Backlit & statement pendant necklace designs
• Standard oval bezel & pendant settings
• Resin casting — stone glows within resin under light
• Crystal healing & light energy work
• Boho & artisan jewellery collections
• Collectors of rare & unusual natural gemstones

✦ What Makes This Stone Special:
Partial translucency in Seam Agate occurs naturally where silica-rich layers within the stone are thinner or purer in composition. This creates a softly glowing section that contrasts beautifully with the opaque banded areas — a quality highly prized by collectors and jewellery designers who want a stone with depth, mystery, and living light play.

At 22x13mm this is a versatile mid-size oval — slender enough to sit elegantly on the neckline yet large enough to showcase the translucent glow with impact. The standard 5mm dome gives the stone excellent depth and rich light play across the polished surface, enhancing the glowing translucent effect beautifully.

When set in a wire-wrapped pendant and worn, natural light from the environment backlights the translucent section throughout the day — creating a living, ever-changing glow that no opaque stone can replicate.

✦ Photography Tip:
Photograph this stone held up to a bright window or lamp so light shines through the translucent section. This backlit glow shot will be your most powerful listing image — it instantly communicates what makes this stone rare and will stop buyers mid-scroll. Add "See photo 2 for the glowing effect" in your first description line.

• 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.

✦ Perfect For:
• Drop pendant & directional necklace designs
• Wire wrapping — tapered point provides strong anchor
• Modern & geometric jewellery collections
• Art deco & architectural jewellery styles
• Statement ring with angular setting
• Gothic & alternative jewellery designs
• Crystal healing & energy work
• Collectors of bold geometric gemstone shapes

✦ Why This Elongated Triangle?
The 24x13mm proportions set this stone apart from both smaller compact triangles and larger equilateral cuts. Its near 2:1 length-to-width ratio produces a sharply tapered silhouette — broad and confident at the top, narrowing decisively to a strong point below.

This elongated form creates a natural sense of downward movement and direction — making it particularly powerful as a drop pendant where the point hangs below and draws the eye. In ring settings, the elongated triangle visually lengthens the finger in the same way a marquise does, adding elegance and drama.

The pointed tip is a practical advantage for wire wrappers — the sharp lower apex provides a strong, natural anchor point, while the wider flat top edge offers ample surface for decorative wrapping work.

At 8.5 carats with a 4mm dome, this stone has solid substance without being heavy — a comfortable weight for pendant wear while still carrying real visual presence.

✦ 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 contrast between the organic, flowing natural agate banding and the sharp, angular elongated triangle silhouette creates a uniquely compelling visual tension — earthy and geometric, natural and bold, all in one stone.

Celebrated for its grounding and stabilising energy, Seam Agate is beloved by crystal practitioners and artisan jewellers worldwide.

Bring bold geometric character to your everyday jewellery with our Natural Seam Agate Small Triangular Cabochon — a charming 15x13x4mm gemstone weighing just 5 carats, cut into a compact triangular silhouette that delivers modern, geometric style in a dainty, lightweight package.

At 15x13mm 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: 15 x 13 x 4 mm
• Weight: 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 15x13mm and 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 (15mm wide x 13mm 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 4mm 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.

Make a truly bold statement with our Natural Seam Agate Heart Shape Cabochon — a striking 26x17x6mm gemstone weighing 18 carats, featuring a wide, expressive heart silhouette and the deepest dome in our heart collection at 6mm.

This is a heart cabochon with real presence. The wider-than-tall proportions of 26x17mm produce a broad, open heart silhouette — full, expressive, and immediately recognisable from a distance. Combined with an impressive 6mm dome that rises generously above the surface, this stone has exceptional visual depth, rich light play, and a tactile quality that smaller, flatter stones simply cannot match.

✦ Stone Specifications:
• Shape: Heart
• Dimensions: 26 x 17 x 6 mm
• Weight: 18 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:
• Bold statement pendant & necklace designs
• Wire wrapping & oversized heart bezel settings
• Statement heart ring centrepiece
• Valentine's Day & anniversary jewellery
• Crystal healing & heart chakra work
• Luxury gift for gemstone collectors
• Bridal & special occasion jewellery making

✦ Why This Heart Stands Out:
At 26x17mm, this is one of the widest heart cabochons in our collection. The broader-than-tall proportion gives the heart a full, expressive, open silhouette — not the narrow, elongated heart of some cuts, but a wide, classic heart that reads boldly and clearly.

The 6mm dome is the defining feature that elevates this stone above all others. This is the deepest dome across our entire heart range — creating a generous, rounded profile with exceptional light play across the polished surface. From every angle this stone catches light and draws the eye.

At 18 carats this is a substantial, high-quality stone with real weight. Experienced collectors and jewellers will immediately recognise the premium natural material and deep dome as marks of a genuinely superior cabochon.

✦ 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.

In crystal healing traditions, the heart shape combined with Agate's grounding energy makes this a powerful choice for heart chakra work — promoting love, compassion, and emotional strength.

Introduce timeless natural elegance to your jewellery designs with our Natural Seam Agate Pear Shape Cabochon - a beautifully proportioned 26x16x5mm gemstone weighing 13.5 carats, cut into a full-bodied teardrop silhouette that perfectly balances length, width, and visual presence.

At 26x16mm this pear cabochon has a wider, fuller body than slender teardrop cuts, giving it a rich and substantial presence that showcases the natural banding of Seam Agate across a generous surface area. The classic rounded top transitions smoothly into an elegant tapered point - a timeless silhouette that jewellers have loved for centuries.

STONE SPECIFICATIONS:
- Shape: Pear (Teardrop)
- Dimensions: 26 x 16 x 5 mm
- Weight: 13.5 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 and drop necklace designs
- Wire wrapping and bezel settings
- Pear-shaped ring centrepiece
- Dangle earring settings
- Bridal and occasion jewellery making
- Boho and artisan jewellery collections
- Crystal healing and energy work

WHY THIS PEAR?
The 26x16mm proportions give this stone a well-rounded, full-bodied teardrop form - noticeably wider than slender pear cuts. That extra width means more natural banding visible across the face of the stone, more surface area for wire wrapping, and a richer, more substantial look when worn as a pendant.

The near 1.6:1 length-to-width ratio produces a classic, balanced teardrop - neither too elongated nor too stubby. This proportion is widely regarded among jewellers as one of the most flattering and versatile pear ratios for pendant and ring settings alike.

The 5mm dome adds excellent depth and light play across the polished surface, giving this stone a rich, full presence that catches the eye from every angle.
