SGL Labs Surat Experience Centre is a diamond certification lab in Katargram, Surat, found at RJD Business Hub on Kasha Nagar Road. Surat is known globally for diamond cutting and polishing in India. SGL serves diamond manufacturers, exporters, and jewellery makers across the city.
The centre examines natural and lab-grown diamonds, coloured gemstones, and finished jewellery. Its on-site gemologists check each item independently. Surat’s diamond industry moves quickly and handles high volumes, so manufacturers and exporters get fast, reliable grading without sending stones outside the city.
Every report follows SGL Labs’ standard grading process, covering the 4Cs for diamonds and full jewellery material checks. Our team also uses AI screening tools and Diamond DNA solutions to carry out extra checks. These reports are trusted by traders and buyers in India and other countries. Clients can bring individual stones or full consignments to our Surat centre for grading and certification. Before submission, our team will confirm which report you need and how long the process will take.
Our on-site gemologists prepare the documents and issue the report without sending items to another lab. You can view every certificate online by entering its report number.
