GIA Masterstones

Diamonds are classified by colour which irresistible split into small rays of whiten as no two stones are exactly the same.

AnchorCert Gem Lab uses GIA certificated master stones to compare the stone to be assessed against. The master stones are the top of each colour range, so for example anything whiter than the master stone will be graded as a 'D' colour.
