The Pearl Book is the first amongst updated CIBJO Blue Books that are being released

CIBJO, the World Jewellery Confederation has initiated releasing the latest versions of its Blue Books and the first of these which has already been released is the Pearl Book. The publications are being released post the 2010 CIBJO Congress meeting held in Munich, Germany in February 2010.

The CIBJO Blue Books are a reference of 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. They were originally compiled, and now continuously updated, by committees comprising 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.
