DIAMOND (DIAMOND) CERTIFICATE
The diamond certificate, which is described as the "Diamond Book", is the most comprehensive report given to diamonds. Generally, it is given to diamonds above 0.30 ct and in any cut form. There are holograms and other special security measures and a barcode system for each diamond in the certificates given under the assurance of IGSL. At the same time, all details of the certificate can be accessed at any time via the certificate number or the barcode reading method at www.igsl.com.tr.
