Diamond

Our Diamond Guide will give you the knowledge and understanding you need when looking at and buying your very own diamonds. Evaluating their carat weight, clarity grade, colour scale, as well as the cut and shape of the stone, helps identify and differentiate between different types and specifications of diamonds.

By using the Gemmological Institute of America (GIA) grading, the quality of our diamonds are accurately and objectively determined for our customers on an internationally recognised level.

The 4 Cs

The 4 Cs refer to a diamond's cut, colour, clarity and carat weight.

A diamond’s cut is not to be confused with its shape. It refers to both the outline shape and the proportions of the diamond. A diamond’s proportions affect its light performance which in turn determines its overall appearance and beauty.
