DDA Group is involved in every stage of diamond trading. Our offices in London, Cape Town, Antwerp, Dubai, Hong Kong and Shanghai, oversee every step of the diamond journey. This includes, investment in diamond exploration and mining around the world, diamond buying operations in several countries, rough diamond auctions, cutting and polishing, financing diamond trade, sales of polished diamonds, design, production and sales of our fine jewellery collection, Iris Alexander.
Our business prides itself on the professionalism and experience in which we conduct our business – with safety, reliability, fairness, and goodwill. We strive to deliver the best product at the best price, with a passion and artistic vision for creating magnificence through one of the Earth’s rarest and most beautiful creations. Our journey is a shared passion with our customers and partners. We source quality rough diamonds from auctions in South Africa, Belgium and Dubai, in addition to direct purchases from our diamond industry network. We also maintain our own buying operations based in several African countries, purchasing stones from small local producers, witnessing the direct mining of stones as they are retrieved from the ground. This allows for rigorous vetting of ethical practices, consistent with our purchasing policies – only sourcing from legitimately certified sources who abide by the Kimberley Process. Our private equity fund, Sinolux Capital , allows us to invest in diamond companies which provide funding solutions to the diamond trade. This provides the advantage of extending our industry network, and widens our access to excellent quality rough diamond product.
Selected rough diamonds are cut, polished and certified, which are either offered in the market to jewellery producers, or used in the production of our own fine jewellery collections. Rough diamonds are sold in auctions conducted by one of our companies, DDA Trading BVBA in Antwerp, Belgium, using our proprietary online diamond trading platform. Prior to each auction, our clients can inspect offered diamond parcels at viewings held in Antwerp, Dubai or Hong Kong. In addition to our own production, DDA Group also organises viewings and sells third party goods on its online platform; offering financing solutions to both buyers and sellers.
Selected polished stones are used in the production of our own fine jewellery collection, Iris Alexander . Each collection is limited to ten to fifteen individually designed and hand crafted pieces which are sold to a private audience, by invitation only. Diamond jewellery holds a legacy of fine craftsmanship, design and magnificence, and is the ultimate achievement of trading diamonds. By producing jewellery collections, we hold a deeper connection and understanding of trends and the preferences of our customers. In doing so, we receive enriched knowledge which allows us to better service the industry. We believe it is a pleasure, a privilege and a challenge to have a diamond bestowed upon our workbench. To realise the true potential of a diamond’s magnificence through the creation of fine diamond jewellery, sets a high benchmark which we thrive to maintain.
Our collections of fine diamond jewellery are the work of a carefully selected team of esteemed designers and producers.
We honour every diamond we produce for our collections; showcasing its unique beauty through artistry, impeccable craftsmanship and flawless execution. Our designs ensure a consideration for its wearer, a passion for the female form, and a reverence to the occasion in which it is worn.
