Seam Agate Free Form Cabochon 21x17mm 10ct – Natural Gemstone

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.

✦ 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.
