We offer diamonds graded by GIA

Diamond certificate

Every diamond sold by DALBY DIAMONDS has been analyzed and graded by gemologists from the world’s foremost authority on diamonds: Gemological Institute of America (GIA). Most of our diamonds are laser engraved with a unique GIA tracking number, that whilst invisible to the unaided eye, allows for its origin to be traced -all the while protecting the perfection of the stone.

A diamond by DALBY DIAMONDS comes with either a diamond grading report, diamond dossier® or a diamond quality document from GIA. The diamond is evaluated at the diamond grading lab by a team of skilled gemologists with observation, as well as with a number of scientific tools to document the dimensions, color, clarity and carat weight of the diamond.
