GIA Certified Diamonds

Goldsmiths strive to source the finest diamonds for our jewellery pieces, and to that end, we aim to incorporate, where possible, independent assessments for a selection of precious stones. We work with independent institutions to provide detailed reports on a select number of stones, including the Gemological Institute of America (GIA), the global authority on diamonds, who rank our finest diamonds according to the “Four C’s” - a diamond’s cut, colour, clarity and carat. These detailed assessments from the GIA and other institutions enable you to make a well-informed decision on your diamond purchase.
