Why Choose BGI
- BGI received permission for the name from the Ministry of Industry in 1999.
- The BGI worked for the Foreign & Commonwealth Office (FCO) that has a Government Diamond Office Department, taking part in discussions about the Kimberly Process which is a way to protect buyers from buying conflict diamonds.
- The BGI is used by old established companies such as:
- Christie’s auction house
- Cartier’s Jewellers
- Petrou Antiques
- The BGI is consulted by the police and HM Customs as well as SOCA and anti-fraud agencies around the world about gem value and authenticity.
- During the colour grading process the gem is matched to Official GIA Master stones supplied by Lazare Kaplan in New York for an internationally recognised quality.
- The BGI is accredited by the United Kingdom Government Dept. of Trade & Industry (DTI).
- The BGI also uses FTIR, UV-vis-NIR, Raman, X-Ray and Photo-Luminescence methods of spectroscopy.
- The BGI Laboratory Precision Grading System was developed in 1998. This method acheives higher accuracy by refining each colour into finer 1% sub-divisions.
