A diamond's certification provides you with the best possible information about the diamond you are buying. The certificate includes information such as, colour, clarity, size, measurements, the grade of the cut, polish, symmetry and more. It provides you with total transparency concerning the product you are purchasing, and your certificate is authenticated to the diamond itself by a special laser inscription, containing the certificate number and Swana logo, on each Swana diamond.

We at Swana have decided to certify every diamond with the largest gems laboratory in the world - IGI, renowned for its quality of grading, industry education, and with a global network of laboratories. Each of our diamonds includes a grading certificate issued by IGI.
