The 7 C’s of Our Diamond


diamond’s carats indicate its weight, an indispensable element for its evaluation. It is measured in metric carats (ct); a carat is equal to one-fifth of a gram. The diamonds in our jewelry are available in different caratages.


The cut indicates both the shape the gem is cut in and the proportions of the diamond’s cut. The cutter’s skill unveils the beauty lying hidden in the rough stones. We only use diamonds with high-quality cuts, proportions, and symmetry.


The degree of colour defines the degree of colourlessness. The classification uses the letters of the Anglo-Saxon alphabet from D (perfectly colourless and rare diamonds) to Z (diamonds with intense colouring). When choosing diamonds for its jewellery, Damiani only selects those from D (the purest and rarest diamonds) to I, for absolute chromatic excellence.


The purity of a diamond indicates the presence, number, position, and size of any inclusions (traces of minerals) that are only visible with 10x magnification. The purity establishes its degree of perfection. We only select gems of extraordinary quality.


Our rings offer a perfect fit thanks to our exclusive “comfort fit” design. This exceptional structure and rounded profile make the ring pleasant and comfortable to wear.
