Seam Agate Heart Cabochon 26x17mm 18ct – Deep Dome Natural Gemstone

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.

✦ 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.
