WHAT IS A DIAMOND CERTIFICATE?

A diamond certificate, also known as a diamond report, is issued by an accredited independent gemological laboratory where diamonds have undergone the strictest quality assessment.

In addition to the diamond's measurements, a certificate includes grades for the diamond's colour, clarity, cut and carat weight. These are also known as the "4C's" (see our "Diamonds and the 4C's" guide).All of Bicknells diamonds are graded by the most respected and renowned diamond grading laboratories in the world.  Having our diamonds graded by these laboratories gives you absolute reassurance of the diamond's quality. We use the following;

GIA

(Gemological Institute of America) whose report is considered the benchmark to which all others are compared.

IGI

(International Gemological Institute) who certificate is a standard of excellence for industry professionals and consumers around the globe.
