Cushion natural diamonds

The cushion is a square or slightly rectangular diamond with softly rounded corners and larger facets, with a romantic, vintage character. Cushions vary a lot in faceting and outline, so compare the photographs and the length-to-width ratio (1.00 for square, around 1.10–1.20 for a gentle rectangle).

About cushion diamonds

Questions

What is a good length-to-width ratio for a cushion diamond?

Cushions vary a lot in faceting and outline, so compare the photographs and the length-to-width ratio (1.00 for square, around 1.10–1.20 for a gentle rectangle).

Are these diamonds natural?

Yes. Every centre diamond we offer is a natural, mined diamond graded by an independent laboratory, and the laboratory is named on its certificate.

Can I buy the diamond on its own?

Yes. Choose “Or buy this diamond on its own” on any diamond page, or set it in one of our 18K gold settings.
