CIBJO releases gemstone Blue Book


Manual is a guideline for gemmological terminology and nomenclature.

CIBJO, the World Jewellery Confederation, has released an updated version of its Gemstone Book.

The book is part of the CIBJO Blue Books series, which are a definitive set of standards for the grading, methodology and nomenclature standards for diamonds, coloured gemstones, pearls, precious metals and gemmological terminology and nomenclature.

The CIBJO Blue Books are compiled 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.
