The GIA Certificate
Butler & Rose diamonds are selected with expert care and attention. We are known for only choosing stones of exceptional quality and value that will sparkle and bring joy to the wearer.
As further quality assurance, each Butler & Rose diamond comes with certification from the Gemological Institute of America (GIA), creator of the 4 C’s and the world’s largest most well-respected institute of gemological research and standards.
Established in 1931, GIA is the world’s foremost authority on diamonds, coloured stones and pearls. A public benefit, non-profit institute, GIA is the leading source of knowledge, standards and education in gems and jewellery.
