Diamonds are graded worldwide based on the 4Cs (Carat, Cut, Clarity, Colour).

• Carat: The carat number indicates the weight of the stone. The stone size varies depending on the model for our items. The carat details can be found in our Fine Jewellery items in the item details.
• Cut: THOMAS SABO uses diamonds cut with facets. Diamonds in the Fine Jewellery collection feature the classic brilliant cut.
• Clarity: Most diamonds have tiny natural features called inclusions. The smaller and fewer the inclusions, the better the light can penetrate the stone. THOMAS SABO uses SI grade diamonds.
• Colour: THOMAS SABO uses white diamonds with the colour definition G/H.
