Press Release: With fewer than five weeks before the opening of the 2014 CIBJO Congress in Moscow on May 19, 2014, the fourth of the CIBJO commissions' special reports has been released. Prepared by the CIBJO colored stone commission, headed by Nilam Alawdeen, the report focuses on the proper disclosure of gemstone treatments and modifications, and, in particular, about how lead glass-filled rubies should be properly qualified

In his report, Alawdeen explains that, in the case of heavily glass-filled rubies, CIBJO requires that they be classified as "Ruby and Glass, and described as a "manufactured/composite material or product." In addition, in order to properly protect consumers, the inherent instability of heavily glass filled rubies and other varieties of corundum should also be conveyed as part of the disclosure requirement.

Relating to the global method of colored gemstone disclosure that CIBJO, the American Gem Trade Association (AGTA) and the International Colored Stone Association (ICA) agreed upon in 2010, Alawdeen writes, "the international disclosure coding system has been in existence for four years already, but unfortunately it's still seldom used. Consequently, this is an opportune time to remind the industry of the need for disclosure and traceability and that a practical system is available to do this."

However,  Alawdeen adds the disclosure codes are meant for the use of the trade and industry only. A more detailed explanation of the treatment or modification must be provided to the consumer.

The 2014 CIBJO Congress will take place in Moscow,  with pre-congress meetings on May 17 and May 18. The congress will be hosted by the Russian Jewellers' Guild, whose headquarters will also serve as the main congress venue.

The official hotel is the five-star Hotel Nikol'skaya Kempinski, one of Moscow's most prestigious establishments, which is offering special low rates for attendees of the CIBJO congress. Located in an historic building that was constructed in 1870, it is located in the heart of historic Moscow, within short walking distance from the Kremlin, Red Square and the Bolshoi theatre.
