Seam Agate Triangle Shape Cabochon 19x12mm 7ct – Natural Gemstone

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.

✦ 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:
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 — and with a Triangle 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.

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