A diamond certificate (or grading report) is a document that records the properties of a diamond such as quality, size, the grading of the diamond according to the 4 Cs (colour, cut, clarity, carat weight). The certificate is usually, but not always prepared by expert gemmologists working in independent gemmological laboratories.

Some diamonds sold by All Diamond are accompanied by a diamond certificate from the Gemological Institute of America (GIA) the leading independent diamond grading organisation.

Some jewellers refer to diamond certificates as diamond grading reports, diamond dossiers or diamond quality document.

The diamond certificate that accompanies our diamonds confirms the quality of the diamond, that it is a natural diamond, and confirms proof of your ownership. You could think of a diamond certificate as the diamond's passport or identity card.
