GCS Certified Diamonds
Gemmological Certification Services (GCS) is an independent, London-based laboratory. GCS diamond certificates provide a full Four Cs assessment, and diagram of characteristics.
In the diamond report, the diamond colour, clarity, cut and carat weight are outlined, as well as the proportions and fluorescence of the stone. Furthermore, each diamond report carries two signatures from gemologists with years of experience.
Purchasing a certified diamond from a reputable gemmological laboratory such as GCS is highly recommended to ensure complete transparency in the quality of the diamond.
