CIBJO publishes colored stone special report

The third of the CIBJO commissions' Special Reports has been released a month before the opening of the 2013 CIBJO Congress in Tel Aviv on May 7, 2013.

Prepared by the CIBJO Coloured Stone Commission, headed by Nilam Alawdeen,  the report  reviews updates already made to the Coloured Gemstone Blue Book and also those that are being considered. In particular it looks at the nomenclature used to describe gemstone treatments.

The special report notes the addition of the qualifying terms "laboratory-grown" and "laboratory-created" as alternatives to the term "synthetic," but points out that in the event that a national jewelry association in a non-English speaking country, which is a member of CIBJO, deems that there is no acceptable local direct translation of the terms "laboratory-grown" or "laboratory-created," then only the translation of the term "synthetic" should be used.

The special report states the intention of the Coloured Stone Commission to tackle the inadequacy of current nomenclature in describing lead-glass filled rubies. "If 'composite' is not the right term," it says, "CIBJO should work in haste to adopt the proper nomenclature, to better protect consumers' interests and, thereby, the integrity of the industry."
