ONLINE INVENTORY BACK Rough Diamonds Rough diamonds. The ugly duckling that precedes the swan. Located in Antwerp, Taché’s rough diamond division manages sourcing, production, marketing, investment activity – everything associated with rough stones. Our rough diamonds come primarily from markets in South Africa, Botswana, Angola, Canada, Russia, Australia, and western Africa, but they all make their way to Antwerp. There, they receive strict quality control inspections and sorting. The rough diamonds we offer include everything from “Indian goods” (the trading term for low-end commercial products) to high-end sawables and crystals in a wide range of sizes, colours, and clarity. ORIGINS INDUSTRIAL PREPARING SERVICE ORIGINS Institutional supply Rock-solid relationships with the world’s best suppliers. DE BEERS Since 1975, Taché has been a DE BEERS Sightholder. As a Sightholder, Taché (NV) can provide you with consistency and reliability of supply. ALROSA Alrosa accounts for 25% of the world’s rough diamond production by value and is the largest producer by volume. Thanks to our direct contractual agreement from them, we have been known as “the Russian specialists” for over thirty years. MORE Non-Institutional We’ll go to the ends of the earth to acquire rough diamonds. Quite literally. Africa Africa accounts for more than half of the world’s diamond production. Over the years we have developed a direct and indirect presence on the continent. We continuously try to diversify our sources of rough diamonds, such as sights, off-takes and alluvial artisanal mining. Canada Canada is an alternative diamond producer, and we have access to several sources there. We participate in all rough diamonds tenders from major Canadian diamond productions such as Diavik from Rio Tinto and Dominion's Diamond Corporation Ekati mine, as well as from junior miners. INDUSTRIAL A luxury product contributing to the welfare of society. Industrial diamonds are valued mostly for their hardness and abrasive qualities which makes them the ideal material for cutting and grinding tools. In addition, they have superb thermal conductivity which makes them the ideal material for advanced specialist industrial and scientific uses. Industrial diamonds are used in industries such as aeronautics, automotive, medical, printing and electronics, all of which manufacture products vital for everyday life. The Industrial diamond sector was added in 2014 to Taché’s rough diamond offering. Taché’s preparing subsidiary, Taché-HSK, completed the strategic acquisition of L. M. Van Moppes & Sons Ltd (est.1893), a De Beers Industrial Sightholder, and leading distributor of industrial natural diamonds. PREPARING SERVICE Some rough diamonds are especially challenging to prepare. How fortunate that we love a challenge. Taché offers its clients a preparing service through its Taché-HSK subsidiary. This service provides manufacturers with ready-to-polish stones derived from challenging types of rough diamonds and offers a bit of predictability in an uncertain world in terms of production yield and quality. So that we can reliably provide a high-quality product of this kind, we established a factory in Sri Lanka over a decade ago. Today, it features state-of-the-art technology and a workforce of more than 250 highly trained employees. Taché-HSK’s extensive experience, exacting standards, and growing clientele around the world make us the undisputed leader in this specialized field.
