Seam Agate Heart Cabochon 23x24mm 20ct – Natural Gemstone Pedra Gems

Discover a heartfelt natural treasure from Pedra Gems — our Natural Seam Agate Heart Shape Cabochon, a beautifully proportioned 23x24x5mm gemstone weighing 20 carats, cut into a full, upright heart silhouette that radiates warmth, balance and natural beauty.

At 23x24mm this heart is almost perfectly square in its proportions — just 1mm taller than wide — producing one of the fullest, most satisfying heart silhouettes in our collection. The lobes are deep and rounded at the top, flowing down to a strong, decisive central point that gives the heart its most classic and universally recognised form.

✦ Why This Heart?
The near-square 23x24mm proportions place this stone in the sweet spot of the Pedra Gems heart collection — larger and more substantial than our mid-size hearts (19×19mm, 20×19mm) yet more intimate and refined than our larger statement pieces (24×25mm, 26×29mm).

At 20 carats this is a confident, premium-weight stone. Heavy enough to feel truly special in the hand and meaningful as a gift, yet perfectly proportioned for comfortable everyday pendant wear. The 5mm dome adds excellent depth and rich natural light play across the polished surface.

The slightly taller-than-wide proportion — just 1mm of difference — gives this heart its beautifully upright, full character. The lobes curve generously at the top, the sides taper naturally inward, and the central point drops cleanly below — the heart silhouette at its most complete and satisfying.

✦ 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 from Pedra Gems 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 — promoting love, compassion, emotional balance and inner strength.
