By establishing and upholding the standards used to gauge gemstone quality, the Gemological Institute of America safeguards both buyers and sellers of all gemstones. We are proud to be associated with the GIA (Gemological Institute of America), one of the best laboratories for examining and grading gemstones and jewellery.

GIA operates independently of business and private affairs, governmental lobbies, and advocacy organisations as a non-profit organisation.

To ensure unbiased evaluation, all gemstones are analysed in complete customer confidentiality. As a result, buyers and sellers of gemstones all over the world regard GIA-certified gemstones as the most authentic.

The IGI-GTL Lab Certificate is a mark of trust and authenticity, issued after thorough scientific testing and expert gemological analysis. It confirms the gemstone's natural origin, detailing its species, weight, color, clarity, and any treatments or enhancements. Recognized for its high standards, the IGI-GTL certification ensures that each stone meets international benchmarks for quality, providing buyers with complete confidence in the gemstone’s legitimacy and value.

When Gem Research SwissLab first opened, its goal was to provide GRS certification services for diamonds, gemstones, and jewellery to its clients in the gem and jewellery industry.

An independent gemological research lab, GRS GemResearch Swisslab focuses on the determination of source and authenticity reports for gemstones including rubies, sapphires, and emeralds as well as other well-known coloured stones like spinel, tourmaline, garnet, and jade.

Their research laboratories, which are strategically located in key global locations, are outfitted with the most cutting-edge and contemporary technology to recognise and categorise current precious gemstone treatments. Contributions to Gemology, a film documentary and book series produced by GRS, documents ongoing study that has been conducted through travels to the most renowned mines in the world.
