Heart-shaped diamond

A heart shape is formed by two rounded lobes, a defined cleft and a centred point. Small differences in symmetry alter its silhouette more than they do in many other shapes.

Start with the outline

The two lobes should be even and equal in size. The cleft needs to be distinct without becoming too deep, and the point should lie on the centre line. On smaller stones, the setting’s prongs can affect how clearly the heart reads.

Light pattern

Heart-shaped diamonds use a brilliant-style facet pattern. View the stone in motion and check that dark areas do not dominate the centre. A symmetry grade in the report is useful, but it does not replace a visual assessment.

Protect the point

The lower point should be protected by a prong or another supportive setting. The upper prongs should be placed so that they do not obscure the cleft or make the lobes look uneven.

What to compare

• Matching lobes.
• A distinct cleft and centred point.
• Length-to-width ratio and size impression.
• The light pattern in motion.
• How the setting preserves the silhouette.
