Celebrating a peerless heritage with over 125 years of diamond expertise, De Beers has an unrivalled understanding of what makes a diamond extraordinary. The first to introduce the concept of the 4Cs to consumers in 1939, De Beers continues to pioneer and set the benchmark for assessing diamonds.

Today, we are proud to combine the art and science of beautiful diamonds; leveraging the latest and most advanced technology, we also use our expert eye and unique insight to go well beyond the 4Cs to find the world’s most exceptional diamonds for our jewellery.

De Beers’ expert analysis and stringent criteria start with an in-depth understanding of the diamond’s unique crystalline structure, its basic 4Cs and grading report, but also go well beyond these conventional assessments.

Experts at the De Beers Institute of Diamonds individually analyse the perfection of each diamond’s cut and proportions as well as its natural transparency to ensure that every De Beers diamond exhibits a sparkle and brilliance beyond compare. A De Beers selected diamond will always catch the light and sparkle gloriously with Fire, Life and Brilliance. At De Beers, we are delighted to share our excitement and passion for diamonds; our expert Brand Ambassadors are always available to offer guidance to our clients as they embark on their own journey of discovery toward their perfect diamond.
