Independent Gemological Laboratory Certification

In an ever-evolving market with new advancements, techniques, and technologies, we take pride in offering a carefully curated collection of precious stones certified by Independent Gemological Laboratories.

And for items graded by our in-house gemmologist, we also provide you the option to have them independently certified by a Gemological Laboratory—for a fee.

Your precious stone or jewelry will be expertly identified and graded by ALGT, located in the heart of Antwerp world-famous diamond district.

Furthermore for Rubies, Sapphires, Emeralds, and Paraiba Tourmalines it is also possible to request a certificate containing the suggested origin of the stone, which will be determined by its gemological features.
