Our laboratory has the knowledge and instruments needed to thoroughly analyse your jewellery. An DSI Report is an official document in which a jewellery item is authenticated for different purposes, such as insurance, inheritance or purchase. It can also be used to determine the market value of a jewel. These reports provide a general description of the jewel, the diamonds it contains and the precious metals of which it is made.
DSI is the world’s most trusted name in diamond grading and gem identification. With objectivity and expertise as its hallmarks, DSI ensures the integrity and accuracy of every report it issues. DSI tests every material submitted to determine whether it is natural or not, and discloses any treatments discovered during our examination.
