CIBJO, The World Jewellery Confederation, represents the interests of all individuals, organisations and companies earning their livelihoods from jewellery, gemstones and precious metals, covering the entire industry from mine to marketplace in the various production, manufacturing, trading and retail centres.


Arguably the most substantial reconsideration in recent decades of the way in which diamond jewellery should promoted and sold was the focus of seminar held September 4, 2016,  in Vicenza, Italy.

CIBJO set up the Jewellery Industry Measurement Initiative to help companies within the jewellery industry understand their environmental impact, reduce it, and protect themselves and the industry as a whole.

The CIBJO Blue Books are definitive sets of grading standards and nomenclature for diamonds, coloured gemstones, pearls, precious metals, and gemmological laboratories.
