CIBJO has made latest editions of all six CIBJO Blue Books available for downloading from the CIBJO website. For those who are not members of a CIBJO-member organisation, each individual download will cost 9.90 Swiss francs while a package of all six Blue Books (Diamond Book, Gemstone Book, Pearl Book, Coral Book, Precious Metals Book and Gemmological Laboratories Book) can be downloaded at a discounted rate of 49.90 Swiss francs. For the members of a CIBJO-member organisation, the CIBJO Blue Books are free of charge and the individual can request the organisation of which they are members to arrange delivery of the relevant Blue Books by email.

The six CIBJO Blue Books are definitive sets of grading standards and nomenclature for diamonds, coloured gemstones, pearls, coral, precious metals, and gemmological laboratories. They are compiled and consistently reviewed and updated by relevant CIBJO Commissions, whose members include representatives of trade organisations and laboratories active in the respective areas of the industry. In the almost complete absence of jewellery industry standards endorsed by the International Standards Organisation (ISO), the CIBJO Blue Books are the most widely accepted set of globally accepted standards.

“The Blue Books are living documents, which are designed to facilitate a common language and benchmarks for members of our industry, irrespective of where they are located,” said Gaetano Cavalieri, President of CIBJO. “We update them from year to year, to reflect changing circumstances, new discoveries and developing technologies.” “The area covered by the Blue Books is considerable, and they reflect the work done by a great many of our industry’s finest minds,” added Roland Naftule, President of CIBJO’s Sector A.
