Diamond Certificates


All our diamonds have been thoroughly inspected and graded by the Gemological Institute of America (GIA), and are accompanied by their own GIA certificate, which covers the diamond’s 4Cs – cut, clarity, colour and carat weight – and a visual diagram of the diamond’s proportions.

It is most likely your diamond will also be laser inscribed with an individual certificate number for identification.

Gemological Institute of America (GIA)

The Gemological Institute of America (GIA) is one of the most respected and recognised diamond laboratories in the world, and diamonds that come with GIA certificates are the most highly valued in the world. They are guaranteed to be graded reliably and consistently, by anywhere from three to six separate gemologists.
