What Is a Heart Shaped Diamond?
A heart shaped diamond is a brilliant-cut stone in the silhouette of a heart — two soft lobes meeting at a cleft, narrowing to a pointed tip — using 56–58 facets, similar to a pear cut.
- Symmetry is everything — the lobes must mirror exactly and the point align below the cleft; even small asymmetries are immediately visible.
- Minimum size — 0.50ct minimum, ideally 1.00ct+; below that the heart silhouette becomes ambiguous.
- Best ratio — typically 1.00 (as tall as wide), acceptable range 0.90–1.10.
Why ATL Luxury Jewelers for Your Heart Engagement Ring
We hold every heart center stone to GIA certification — paying particular attention to the Symmetry grade, which matters more for heart cuts than for any other shape. Every ring includes lifetime cleaning, prong-tightening, and rhodium-plating service.
Heart Shaped Diamond Rings by Carat — 1ct, 2ct, 3ct
Carat size matters more for heart shaped diamonds than for any other shape — below 0.50ct the silhouette becomes ambiguous:
- 1 carat — ~6.5mm × 6.5mm; the recommended minimum for a clearly-readable heart silhouette.
- 2 carat — ~8.5mm × 8.5mm; substantial presence with unmistakable romantic symbolism.
- 3 carat — ~10mm × 10mm; a dramatic statement with cleft and lobes clearly defined from across the room.
All sizes come in natural and lab-grown. Lab-grown heart shaped diamonds typically cost 50–70% less than natural stones of equivalent grade — making larger hearts (2ct+) significantly more attainable. We source GIA-certified stones at your target carat, length-to-width ratio, and symmetry grade for in-person review within 48 hours.
