The World Jewellery Confederation (CIBJO) has released the updated Precious Metals Book, the second in a series of CIJBO Blue Books to be revised. The Pearl Book was the first to be released soon after the February CIBJO 2010 Congress meeting in Munich.
Updates in the new version of the Precious Metals Book include the introduction of a new appendix giving information on precious metal fineness. The appendix can now be lawfully sold in CIBJO Member countries worldwide.
The CIBJO Blue Books are a definitive set of standards for the grading, methodology and nomenclature standards for diamonds, colored gemstones, pearls, precious metals, and recently, also for gemological terminology and nomenclature. The CIBJO Blue Books were originally compiled, and now continuously updated, by a number of committees comprised of representatives from trade organizations and laboratories in the diamond, colored gemstone, cultured pearl, precious metals and jewelry industries. The standards represent a consensus derived from the broad expertise on the subject within these committees, and also from individuals outside the committees who had expressed an interest in participating in the development of the guidelines.
In addition to the Precious Metals book, originally launched in 2007, and the Pearl Book, the CIBJO Blue Books series also includes the Gemstone Book, the Diamond Book and the CIBJO Gemmological Book.
