Buyers Guide

The 4 Cs

The diamond certification standard elaborating the 4Cs was developed by the GIA, an internationally recognised institution. The 4Cs include colour, clarity, cut and carat, and determine the quality of the diamond and its value.

We offer a range of ethically sourced certified diamonds. We choose to use three internationally recognised laboratories:

GIA –  The Gemological Institute of America
IGI -  The International Gemological Institute
HRD –  Antwerp Institute of Gemmology
