Following the 2010 CIBJO Congress meeting that took place in Munich, Germany this past February, CIBJO, the World Jewellery Confederation has begun releasing the latest, updated versions of its Blue Books.The first book to be released since the 2010 Congress meeting is the Pearl Book.

The CIBJO Blue Books are a definitive set of standards for the grading, methodology and nomenclature standards for diamonds, coloured gemstones, pearls, precious metals, and recently, also for gemmological terminology and nomenclature. The CIBJO Blue Books were originally compiled, and now continuously updated, by a number of committees comprised of representatives from trade organisations and laboratories in the diamond, coloured gemstone, cultured pearl, precious metals and jewellery 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.
Initially, the first three publications were printed with different coloured covers; blue for the Gemstone Book, grey for the Diamond Book, and green for the Pearl Book. In 2007, the Precious Metals book was launched and in 2010 the CIBJO Gemmological Book was released. Today, these publications are generally referred to as the CIBJO Blue Books.
