A true family business, Graff is unique in the world of diamonds. As custodians of some of the world’s rarest and most celebrated stones, the incredible collection of precious gems within its vaults is a testament to the expertise, experience and pioneering spirit of the House, whose reputation for diamond excellence is incomparable.  

The GIA employs a color grading scale for white diamonds, ranging from D (colorless) to Z (light yellow or brown). The grading is based on the diamond's absence or presence of color. The color grading process involves assessing the diamond under controlled lighting conditions.

Graff diamonds are exceptionally pure; many are Flawless or display minute inclusions that are invisible to the naked eye. At Graff’s Global Headquarters in London, a team of master artisans employ decades of experience to create jewelry pieces with breathtaking skill and precision, each uniquely crafted to cradle the shining diamond at its heart.

Diamond certification is a document provided by a professional, independent gemological laboratory that details a diamond’s specification, including its cut, color, clarity and carat weight – typically referred to as the 4Cs. 

Carat weight is highly subjective and dependent upon personal preference. When purchasing a diamond, it is also essential to consider the stone’s cut, clarity and color, as these will all determine its overall beauty.
