“Gemmata offers you more than 40 years of experience in the industrial diamond trade”

After a few years of learning the ins and outs of the industrial diamond world, Jan Leemans founded Gemmata in 1982 in Antwerp, Belgium. The main office is located in the Antwerpsche Diamantkring since the very beginning.
The ‘Kring’ is the world’s leading rough diamond bourse (since 1929) and a founding member of the World Federation of Diamond bourses. It’s one of the 4 Antwerp diamond exchanges and the perfect home base for Gemmata.

Gemmata’s base of operations is its headquarter in Antwerp but throughout the years the company has built up a global network with partners and offices in all 4 corners of the world to help optimize sourcing in Russia, Africa and India. China in particular has always been a mayor market for the company.

Today, Gemmata sources its diamonds globally from Canada and Russia in the North, Africa in the South and India and Australia in the East.
