IDH first started polishing diamonds in Belgium in 1970. However, in the last few years manufacturing has been a key development focus and IDH has invested significantly in building this area of the business. It brought in the expertise of Roman Atlass, one of Antwerp’s most respected technical masters, with over 35 years experience in diamond polishing. IDH has harnessed Roman’s skill to revive its polishing operations with a strategy to build scale and a view to becoming one of the leading suppliers of top-end polished. IDH has set-up manufacturing operations in India and China. Its factories are equipped to a world-class standard and employ highly skilled polishers, enabling IDH to achieve the highest attainable cut standards. Consequently, IDH is an important supplier to some of the world’s most prestigious jewellery houses, who value its premium products of superior beauty.
