Certified Diamonds




GIA Certified Diamonds

All of our diamonds have been thoroughly inspected and graded by the Gemological Institute of America (GIA), and are accompanied by their original diamond grading certificate. The Gemological Institute of America (GIA) is the foremost respected and recognised diamond laboratory in the world, and diamonds that come with GIA certificates are the most highly valued.  We choose GIA certified diamonds as GIA is recognised the world over for having reached the pinnacle of their field and demonstrate consistent diamond grading and high quality analysis.

The GIA certificate ensures that the diamond you purchase is the one you receive; verifying that a diamond is genuine and evaluating a diamond’s characteristics. A certificate will provide information on the 4Cs - Carat, Cut, Colour, Clarity and also information about the diamond's fluorescence, visual depiction of its proportions, measurements and its finish.
