LAB POLICY RELATED TO GEMSTONE REPORT
Access to data
Our Gemstone Reports are freely available to view, verify and download. All the SGL gemstone certification data is maintained systematically and can be presented on demand as a right to consumer perusal limited to the certificate.
SGL is a professional diamond/ Gemstone identification and grading service that uses the latest technology. With specialized services and laboratory-grown detection instruments, SGL makes it easy to identify natural diamonds.
The SGL Gemstone Report/ Certificate is a document that cannot be tampered with or duplicated easily. The special paper, UV text visible under UV/Blacklight, and secured 3D holograms make it difficult to tamper with this document. Our diamond sealing also displays many tamper-evident features, providing peace of mind to the holder of the certificate.
SGL goes to great lengths to protect client confidentiality and anonymity. We use a barcode system and software modules to grade and process diamonds and their Gemstone certificates without ever knowing the client's identity. This ensures that our grading is unbiased.
We provide unique additional services; tailored for your needs to add value to your diamond.
