Why choose a heart shaped diamond?

The heart cut is one of the most technically demanding shapes to cut well, needing exact symmetry between both lobes, and it is the most romantic of all diamond shapes, ideal for engagement rings, pendants and gifts.

How to choose a heart lab-grown diamond

Symmetry. The two lobes should be the same size with a clear cleft and a sharp point. Look for Excellent or Very Good symmetry.

Size. Heart shapes are easiest to recognise at around 0.70 carats and above, especially once set.

Colour and clarity. D to G gives a bright white look; VS1 and VS2 clarity are eye-clean.
