Heart Shape

Celebrate the beauty of natural gemstones with our Natural Seam Agate Heart Shape Cabochon — a beautifully balanced 20x19x5mm stone weighing 14 carats, cut into a classic, full heart silhouette that is as timeless as it is striking.

✦ Why This Heart Shape?
The near-equal 20x19mm proportions of this cabochon produce one of the most classically balanced heart shapes available. Many heart stones are either too wide and flat or too tall and narrow — this stone hits the ideal proportions that give a heart its most recognisable, satisfying silhouette.

The 5mm dome adds generous depth and excellent light play across the polished surface, giving the stone a rich, full presence whether set in a pendant or ring. At 14 carats it carries real weight and visual substance without being oversized.

✦ 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 stability.

✦ Why This Stone Stands Out:
