About GemClub
A Living Reference.
The encyclopedia is a continuously expanding reference - written for retailers, designers and collectors who want substance over sales copy.
GemClub is the educational arm of Nivoda - the world's marketplace for diamonds and coloured gemstones. Where the marketplace powers the trade, GemClub is here to deepen what you know about every gemstone passing through it.
The encyclopedia is a continuously expanding reference: every gem currently traded on Nivoda, written for retailers, designers and collectors who want substance over sales copy. Treatments are disclosed honestly. Care advice is practical. Origins matter.
Members of GemClub receive monthly briefings, on-demand webinars and early access to our long-form editorial - the parts of the trade that don't fit in a product description.
