Add effortless elegance to your jewellery collection with our Natural Seam Agate Pear Shape Cabochon — a slender and graceful 27x12x4mm gemstone weighing 9 carats, cut into a refined teardrop silhouette that is a timeless favourite among pendant and earring makers.
This slim pear cabochon strikes a beautiful balance between length and delicacy. At 27mm long and just 12mm wide, it has an elongated, slender profile that hangs with natural elegance — perfect for pieces where grace and movement matter as much as the stone itself.
✦ Stone Specifications:
• Shape: Pear (Teardrop)
• Dimensions: 27 x 12 x 4 mm
• Weight: 9 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:
• Elegant drop pendant & necklace designs
• Dangle & drop earring settings
• Wire wrapping & slim bezel settings
• Bridal & occasion jewellery making
• Boho & minimalist jewellery styles
• Crystal healing & energy work
✦ Why This Pear Shape?
The 27x12mm proportions of this stone give it a slender, elongated teardrop form that is noticeably more refined than wider pear cuts. This slim profile makes it especially well suited for dangle earrings where symmetry, light weight, and graceful drop movement are essential.
The pointed tip provides a natural anchor point for wire wrapping, while the smooth rounded base adds elegant visual balance. The 4mm dome keeps the profile low and wearable — comfortable for earrings or everyday pendant wear.
At just 9 carats, this stone is lightweight enough for earring use without sacrificing visual presence — an important consideration that heavier stones cannot offer.
✦ 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.
Celebrated for its grounding and calming energy, Seam Agate is beloved by crystal practitioners and artisan jewellers worldwide. Its warm tones pair beautifully with sterling silver, gold-filled, and copper wire settings.

Discover a truly rare natural treasure — our Natural Seam Agate Free Form Cabochon, a captivating 28x14x5mm gemstone weighing 15 carats, featuring a remarkable partial translucency on one side that allows light to pass through like a glowing window.
This is not a common feature. Most Seam Agate cabochons are fully opaque — but this individual stone carries a naturally translucent section on one side where the agate thins and clears, creating a beautiful interplay of light and shadow across the stone's surface. Hold it to the light and watch it glow.
✦ Stone Specifications:
• Shape: Free Form (naturally contoured organic silhouette)
• Dimensions: 28 x 14 x 5 mm
• Weight: 15 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, domed top)
• Finish: High-polish, smooth surface
• Special Feature: Partially translucent on one side — 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.
• Shape note: Free form stones are unique by nature — the silhouette, banding pattern, and translucent area of this stone are individual characteristics that will not be replicated in any other piece.
✦ Perfect For:
• Wire wrapping — the translucent area glows beautifully when light hits the wrapped pendant
• Backlit pendant & statement necklace designs
• Electroforming & copper wrap projects
• Boho, artisan & nature-inspired jewellery
• Crystal healing & light energy work
• Collectors of rare & unusual natural gemstones
✦ The Translucency Feature:
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 with the opaque banded areas — a characteristic highly prized by collectors and jewellery designers who want a stone with depth, mystery, and light play that no fully opaque stone can offer.
When set in a wire-wrapped pendant and worn, light from the environment naturally backlights the translucent section throughout the day — creating a living, ever-changing glow.
✦ 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 translucency — every cabochon is a completely unique piece of natural art.
Celebrated for its grounding and calming energy, Seam Agate is a favourite among crystal practitioners and artisan jewellers worldwide.
Order today and receive this exact hand-selected gemstone — its translucency, shape, and banding are one of a kind and will never be repeated.
Embrace the darker side of natural beauty with our Natural Seam Agate Coffin Shape Cabochon — a bold and striking 28x17x5mm gemstone weighing 23 carats, cut into the iconic coffin silhouette beloved by gothic, witchy, and alternative jewellery makers worldwide.
The coffin shape, also known as a casket cut, features a rectangular body that tapers to a pointed base — a silhouette that is both dramatic and deeply symbolic. Paired with the rich natural banding of Seam Agate, this cabochon is a statement piece that stands apart from anything ordinary.
✦ Stone Specifications:
• Shape: Coffin (Casket)
• Dimensions: 28 x 17 x 5 mm
• Weight: 23 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, domed top)

• Statement coffin ring centrepiece
• Alternative & occult jewellery designs
• Crystal healing & protection work
• Collectors of unusual gemstone shapes
✦ Size Reference:
Not sure how big this stone is? At 28x17mm 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 23 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.

Discover a truly one-of-a-kind gemstone with our Natural Seam Agate Free Form Cabochon — a beautifully organic 21x17x4mm stone weighing 10 carats, shaped by nature into a captivating blend of an egg-like roundness and a gentle triangular taper.
This free form cabochon is unlike any standard cut. Its soft, rounded body flows naturally into a subtle point, creating a silhouette that is both organic and compositionally dynamic — part egg, part triangle, entirely unique. No geometric tool created this shape; nature did.
✦ Stone Specifications:
• Shape: Free Form (organic egg-triangle mixed silhouette)
• Dimensions: 21 x 17 x 4 mm
• Weight: 10 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 egg-triangle silhouette is a natural characteristic of this individual piece and will not be identical to any other stone.
✦ Perfect For:
• Wire wrapping & freeform jewellery designs
• Organic & boho pendant settings
• Electroforming & copper wrap projects
• Nature-inspired jewellery collections
• Crystal healing & energy work
• Collectors of rare & unusual gemstone shapes
✦ Why Free Form?
Free form cabochons are the most prized stones among creative jewellers precisely because their shape cannot be replicated. Each piece demands an entirely original design — making every finished jewellery piece inherently unique.
The egg-triangle mix of this stone gives it a natural visual tension that standard oval or round stones simply cannot offer. The soft rounded upper body transitions into a gentle tapered base, creating natural movement and a beautiful organic profile.
At 21x17mm and 4mm dome, this stone is a compact yet impactful size — versatile enough for a pendant, ring, or brooch centrepiece without being overwhelming.
✦ 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 flow, or outline — every cabochon is a geological work of art carrying millions of years of natural history.
Celebrated for its grounding and stabilising energy, Seam Agate is a favourite among crystal healers and artisan jewellers alike.
Order today and receive this exact hand-selected gemstone — fully polished, flat-backed, and ready to inspire a design as unique as the stone itself.
Add a burst of natural colour to your jewellery collection with this stunning Natural Seam Agate Oval Cabochon — a large 30x22x6mm gemstone weighing 32.5 carats, featuring a striking combination of red, yellow, and white natural banding.
This bold, multicolour cabochon is one of nature's most vibrant expressions of Seam Agate. The fiery interplay of warm red, sunny yellow, and crisp white layers creates a dramatic visual energy that makes this stone an instant centrepiece in any jewellery design.
✦ Stone Specifications:
• Shape: Oval
• Dimensions: 30 x 22 x 6 mm
• Weight: 32.5 Carats
• Stone Type: Natural Seam Agate
• Colour: Red, Yellow & White 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.
✦ Perfect For:
• Large statement pendant & necklace designs
• Wire wrapping & oversized bezel settings
• Bold cocktail ring centrepiece
• Boho & tribal jewellery styles
• Crystal healing & solar plexus chakra work
• Collectors of vivid, multicolour gemstones
✦ Why This Stone Stands Out:
At 30x22mm and 32.5 carats, this is a large, commanding oval cabochon with exceptional visual impact. The 6mm dome — deeper than most standard cabochons — gives the stone a rich, full profile that catches light beautifully from every angle.
The combination of red, yellow, and white is particularly rare and striking in Seam Agate. Red tones in agate are created by iron oxide inclusions, giving each stone its warm, fiery character. The contrast against white and golden yellow bands creates a natural composition that no designer could replicate.
✦ Colour & Energy:
In crystal healing traditions, the red and yellow tones of this agate are associated with the root and solar plexus chakras — bringing energy, confidence, and vitality. White banding adds a balancing clarity to the stone's energetic profile.
✦ About Seam Agate:
Seam Agate is a natural chalcedony formed within rock seams and fissures, producing richly layered banding patterns unique to every stone. No two pieces are ever alike in colour, flow, or character.

Elevate your jewellery designs with our Natural Seam Agate Pear Shape Cabochon — an elegantly proportioned 26x13x5mm gemstone weighing 13.5 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.
✦ Stone Specifications:
• Shape: Pear (Teardrop)
• Dimensions: 26 x 13 x 5 mm
• Weight: 13.5 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, domed top)

• Wire wrapping & bezel settings
• Boho & elegant jewellery styles
• Crystal healing & energy work
• Bridal & occasion jewellery making
✦ Why Pear Shape?
The pear or teardrop shape is one of the most flattering and popular cabochon cuts for pendant jewellery. At 26x13mm, 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.
✦ About Seam Agate:
Seam Agate is a natural chalcedony formed within rock seams and fissures, producing its characteristic flowing, layered banding in warm, earthy tones. No two stones share the same pattern — every cabochon is a completely unique piece of natural art.
