For the Identification of a gemstone, a laboratory check a gemstone on several gemological parameters like Reflective Index (RI), Optical Character, Specific Gravity, Hardness, Inclusions etc.
Certification by independent gemological laboratories plays a key role in the international gemstone trade, providing assurance to both buyers and sellers. As a dealer, we want to ensure that all the gemstones we sell are exactly as described.
You will find that many of our gems, especially Natural Alexandrite, Unheated Blue Sapphire, Unheated Yellow Sapphires, Kashmir Sapphire, and Salt Water Pearl have certificates included when we offer them for sale. You can view the certificates copy when you visit the detail pages for the relevant gems.
Now a days many of the sellers provide their own certificate which can be fake or partially incorrect.
Therefore, third-party certification holds significant importance and a customer should only rely on third party certification.
For the complete satisfaction of a customer, we include gemstone certificates from independent gemological laboratory. Please check the individual item pages for more information on the certificate accompanying the gemstone.
We provide certificate issued by the following labs:
