The World Diamond Council welcomes five new members


The Choron Group was established in 1985 by Rajesh Gandhi in Antwerp, Belgium. In its early years, it focused on procuring rough diamonds from secondary sources in Antwerp and distributing them in India, while at the same time it was purchasing polished diamonds from manufacturers in India for distribution to clients across Europe and the Far East.

As the business expanded, Choron set its sights on developing relationships with major rough diamond producers. Throughout the 1990s and early 2000s, it solidified its rough diamond supply and was transformed into a leading diamond house. In parallel, it broadened its sales network with offices across the globe.

Today, Choron is focused on the sourcing, assortment and sale of rough diamonds, the manufacturing of exceptional rough stones, the sale of polished diamonds and the distribution of wholesale jewelry.
