IGC Group - Belgian excellence in diamonds 

Proud exhibitor of the ‘BrilliAnt’ Antwerp Diamond Trade Fair’

From January 29 until 31st, 2017 Antwerp will host the 8th Antwerp Diamond Trade Fair within the heart of the world’s oldest and most reputable diamond centre. Visit IGC Group's booth within the Diamond Bourse, booth 7B. We are looking forward talking to you.


Five generations of diamond expertise have underpinned the success of one of the world's oldest diamond firms. Jacques Claes, assisted by his father Frans Claes, a diamond cutter, established the company in 1912.

A major milestone in IGC Group’s history was the establishment of a large polishing factory in Thailand in 1980. Since then, two more factories have joined the group: one in Laos in 1999 and another in Botswana in 2007.

Known all over the world for its finest make, IGC Group is a strategic diamond partner for the Swiss watch industry, high-end retailers and jewellery manufacturers worldwide.
