Heart-shaped engagement rings that don't look childish

A heart can look elegant or like a costume ring. The difference is almost entirely symmetry and setting. Here's what to check, and the Segal heart we'd pick.

By The Loupe & Band editors. Updated . Our picks come from Segal's published specs, prices and policies. How we choose

What makes a heart look good

Symmetry. The two lobes should be the same size and the point should sit in the centre. Heart cuts vary more than any other shape, so look at a photo of the specific stone.

A clean setting. The heart shape is already the statement. A simple band and neat prongs let it read as jewellery rather than a novelty. That's why we like Noelle: a heart on a plain band, nothing else competing with it.

Enough size. Small hearts blur into triangles once set. If budget is tight, choose a lab-created diamond or moissanite at a larger size rather than a tiny natural stone.

Questions people ask

What size should a heart diamond be?

Hearts under about half a carat lose their shape once prongs cover the edges. Around one carat and above, the outline reads clearly.

How many prongs does a heart need?

Usually three: one at the point and two at the lobes, or a V-prong protecting the point, which is the most fragile part.

Are there matching earrings?

Segal sells Noelle heart diamond earrings, which make an easy anniversary gift later.
