IDH is a pioneer in developing rough diamond trading systems and offering technical consultancy. It works with the full spectrum of rough diamonds, and is particularly specialised in processing Run of Mine productions. IDH distributes to a wide range of customers around the world, through offices in the main diamond trading and processing centres: Antwerp, Mumbai and Surat. It has a network over 900 diamond companies with over 300 active customers. IDH’s primary expertise is in supplying small manufacturers, who rely on its precise, consistent and accurately priced assortments to maintain their own operational efficiency. IDH has developed proprietary inventory management and pricing systems. This allows any rough parcel to be tracked back to its origins, irrespective of splitting and assorting stages. The depth of IDH’s market insight and pricing intelligence underpins its consulting capabilities. Over the years, some of the world’s leading rough producers, including De Beers, Rio Tinto and BHP Billiton, have retained IDH’s technical expertise and market acuity in designing and developing their own distribution systems. IDH currently receives a regular direct supply from RTD and BHP Billiton.
