XL Seam Agate Heart Cabochon 26x29mm 35ct – Natural Gemstone

Presenting our most impressive heart cabochon — the Natural Seam Agate XL Heart Cabochon, a breathtaking 26x29x6mm gemstone weighing a full 35 carats. This is the largest, heaviest, and most dramatic heart stone in our entire collection, and it shows.

At 29mm tall and 26mm wide, this is a genuinely large heart — taller than it is wide, producing an upright, elongated heart silhouette with a strong, expressive curvature at the top and a deep, confident point below. The 6mm dome rises generously above the surface, creating a stone with exceptional visual depth, rich light play, and a commanding tactile presence that must be held to be fully appreciated.

At 35 carats, this is a premium natural gemstone of substantial weight and quality — a stone that collectors and experienced jewellers will immediately recognise as something special.

✦ Why This Stone Is Exceptional:
At 35 carats and 26x29mm, this heart cabochon is in a class of its own. To put the size in perspective — at 29mm tall this stone is roughly the size of a large coin, making it a bold, unmissable centrepiece in any jewellery design or display collection.

The taller-than-wide proportions give this heart a deep, upright silhouette — an elongated heart form with strong curves at the lobes and a decisive downward point. This silhouette is particularly dramatic when worn as a large drop pendant, the point hanging below and the full face of the stone displaying its natural banding in all its glory.

The 6mm dome — matching our other deep-dome hearts — rises richly above the surface, adding extraordinary visual depth and a three-dimensional quality rarely seen in agate cabochons of this size. Light plays across the polished dome from every angle.

35 carats in natural Seam Agate is a substantial weight. This is a stone made for someone who appreciates quality, scale, and the raw, unrepeatable beauty of natural gemstones.

✦ 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 stone for heart chakra work — amplified here by the exceptional size and weight, which many practitioners believe deepens the energetic connection.
