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.

Bring bold geometric character to your jewellery designs with our Natural Seam Agate Trapezoid Cabochon — a striking 21x13x4mm gemstone weighing 10.5 carats, cut into the distinctive trapezoid silhouette loved by contemporary and art deco jewellery makers.

The trapezoid shape — also known as the trapeze cut — features four sides with two parallel edges of different lengths, creating an asymmetric angular form that is both architectural and dynamic. When paired with the organic flowing bands of natural Seam Agate, the result is a stone that beautifully bridges natural and geometric worlds.

✦ Stone Specifications:
• Shape: Trapezoid (Trapeze Cut)
• Dimensions: 21 x 13 x 4 mm
• Weight: 10.5 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.

• Modern & contemporary pendant designs
• Art deco & geometric jewellery styles
• Wire wrapping & angular bezel settings
• Statement ring centrepiece
• Minimalist & architectural jewellery
• Crystal healing & grounding work
• Collectors of unusual gemstone cuts

✦ Why Trapezoid Shape?
The trapezoid is one of the most sought-after geometric cuts among modern jewellery designers. Its angular lines create visual interest and a sense of intentional design that round and oval stones simply cannot offer. The wider top edge draws the eye while the narrower base creates natural downward movement — ideal for pendant settings.

At 21x13mm, this stone is a confident, mid-size piece — large enough to make a clear visual statement without overpowering a design. The 4mm dome keeps the profile sleek and contemporary, making it equally suited for ring and pendant settings.

✦ About Seam Agate:

Create bold, directional designs with our Natural Seam Agate Triangular Cabochon — a striking 24x13x4mm gemstone weighing 8.5 carats, cut into an elongated triangular silhouette with a sharp, confident point that commands attention in any jewellery setting.

Unlike compact equilateral triangles, this stone has a pronounced length-to-width ratio of nearly 2:1 — wide across the top with a strong tapered point below, creating a dynamic, directional form that draws the eye downward with natural authority. It is a triangle with movement, tension, and geometric drama.

✦ Stone Specifications:
• Shape: Triangular (Elongated)
• Dimensions: 24 x 13 x 4 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.

✦ Perfect For:

• 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.

Step beyond the ordinary with our Natural Seam Agate Triangle Shape Cabochon — a distinctive 19x12x5mm gemstone weighing 7 carats, cut into a unique Triangle silhouette that cannot be categorised as any standard shape and cannot be replicated in any other stone.

In the gemstone world, "Triangle shape" refers to any custom or non-standard cut that falls outside classic shapes like oval, round, or pear. This stone carries its own individual outline — shaped by the cutter's eye and the natural character of the rough agate — resulting in a piece that is as personal and distinctive as the jewellery made from it.

✦ Stone Specifications:
• Shape: Triangle 
• Dimensions: 19 x 12 x 5 mm
• Weight: 7 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, domed top)

• Electroforming & copper wrap projects
• Statement ring or brooch centrepiece
• Crystal healing & energy work

✦ Why Triangle Shape?
Triangle cut cabochons are the most creatively liberating stones a jeweller can work with. Because the shape is non-standard, it cannot be replicated — every finished piece of jewellery made from it becomes inherently unique. There are no matching bezels, no identical settings — just the freedom to design something entirely original around this one particular stone.

At 19x12mm the stone is a versatile mid-size — substantial enough to be a confident pendant centrepiece while compact enough for a ring or brooch setting. The 5mm dome adds excellent visual depth and a rich polished presence.

✦ 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:

✦ 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.

✦ Why This Small Heart?
At just 13x14mm and 6 carats, this is the most lightweight and wearable heart cabochon in our collection. Its petite size makes it especially well suited for earring pairs where matching stones and comfortable weight are both essential.

The slightly taller-than-wide proportions (14mm tall x 13mm wide) give this heart a naturally upright, classic silhouette — full and recognisable even at small scale. The 4mm dome keeps the profile neat and refined, perfect for low-profile stud settings.

At this size and weight, two of these stones together would make a beautifully matched, lightweight pair of heart earrings — comfortable enough for everyday wear without sacrificing natural character.

✦ 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 popular choice for heart chakra work — promoting love, balance, and emotional warmth.
