Ask any reputable Hatton Garden jeweller of the importance of credible diamond certification and the answer will be unanimous. The GIA (Gemmological Institute of America) is the world’s foremost source of knowledge, standards and education of gems. Whilst there are many laboratories to choose from, only the GIA satisfy the standards required by Rennie & Co jewellers. We stock a beautiful collection of both loose and mounted GIA certificated diamonds in our conveniently located Hatton Garden showroom.

Working with the highest colours, clarities and cuts, each GIA certified diamond is handpicked by André Rennie before being set into the extraordinary engagement rings that you see in our London store. We take an inordinate amount of time choosing our stones, far exceeding the 4C’s remit.

All of the GIA certificated diamonds displayed on this page reflect the loose diamonds that are currently available in-store. A bespoke ring service is on offer allowing customers to create their partner’s engagement ring from scratch. To view our completed GIA certificated diamond rings, simply navigate to your desired category at the top of our website.
