Our jewellery reports are freely available for customers to view, verify and download on demand. We understand that these reports are as precious as your precious metal i.e. gold and hence we take utmost care to offer easy accessibility.
We use latest available technologies to grade the jewelry piece, follow responsible business practices and adhere to international standard throughout the process of jewellery certification.
The SGL Certificate will make your product the ultimate treasure sought by many collectors. It's truly a document that cannot be tampered with very easily and one that can't be forged either. We use techniques such as secured 3D holograms to add in to the security aspect.
