DIAMOND SHAPES

Heart

The most literal symbol of love, and one of the hardest shapes to cut well. How to choose a heart that reads clearly and lasts.

01

A demanding shape

A heart is a brilliant cut with two rounded lobes, a cleft between them and a single point. It takes great skill to cut, because both halves must mirror each other exactly and the cleft must be clear without weakening the stone.

Symmetry and size

Look for even lobes, a well-defined cleft and a point that sits directly below it. Small hearts can be hard to read as hearts once set, so the shape is usually seen most clearly from around half a carat upwards.

03

Colour, clarity and settings

Hearts can show colour at the lobes and point. G to H looks white in platinum or white gold. An eye-clean VS2 is usually enough.

A three-claw setting, one at the point and one at each lobe, shows the outline cleanly; five claws add security. A bezel gives a soft, protective edge. Always protect the point.

What should I look for in a heart shaped diamond?

Even lobes, a clear cleft, a point directly below it, and a ratio close to 1.00.

How should a heart diamond be set?

Three claws, at the point and each lobe, show the shape; five claws add security; a bezel protects it fully. The point should always be covered.
