They thoroughly follow proper stone checking methods, and all details are clearly mentioned on their certificates. This includes:

1. Natural origin of the stone
2. RIBA testing
3. Specific gravity
4. Microscopic view testing

They also comment if the stone is heated, treated, or natural, which is crucial for any certificate.
The International Gemological Institute (IGI) is an international lab with many centres in India, including Delhi, Jaipur, Mumbai, and Bangalore.
IGI is well-known for diamond certification and has been certifying coloured stones for many years.
They update their reports with RIBA, specific gravity, and microscopic view matches, occasionally mentioning the stone's origin.
Knowing the origin is crucial when deciding which stone to purchase.
Both IIGJ and IGI are among the best labs in India. For more information, you can directly call the lab or contact us.
