DCLA granted International Diamond Council Rules for Grading Polished Diamonds

The Diamond Certification Laboratory of Australia (DCLA), Sydney, Australia is proud to announce that it has become only the fifth diamond certification laboratory worldwide to be accepted as grading to IDC Rules.

After a strict and lengthy auditing procedure, DCLA was granted the Rules by Mr. Les Milner of the SAJC.
