At Diamond Manufacturers we offer wholesale diamonds to the trade. Diamonds are sold in parcels and classified into 700 different assortments in a variety of sizes, shapes and qualities. We supply loose diamonds from our own manufacturing as well as independently certified diamonds, mainly from the GIA, IGI and EGL diamond grading laboratories at the highest discounts from Rapaport prices. Our offering prices for GIA, IGI and EGL certified diamonds are between 5 to 15% lower than those offered by dealers to the trade. Upon request we also supply HRD and AGS certified diamonds on a wholesale level. In order to accommodate today’s market demands we also welcome single regular orders from members of the trade with a smaller buying power. To view or purchase diamond parcels email wholesale@diamondmanufacturers.co.uk.

At Diamond Manufacturers we deal directly with the DTC (The Diamond Trading Company), the world’s largest diamond miner. Thanks to our strong supply chain we are able to control the diamond quality from the mine to the end consumer. We only deal with our associated companies whom, like us, proudly adhere to and enforce the standards established by the Kimberley Process, an international system that polices the trade of diamonds to ensure they are from sources free of conflict. All Diamond Manufacturers diamonds are guaranteed to be conflict free. If one of our associates was ever found to be in violation of that process, we would immediately stop working with them. We will continue to support and promote any process that works towards maintaining the human rights and best working conditions in the diamond trade. Diamond Manufacturers is a global strong conflict-free supporter and has a zero-tolerance policy toward conflict diamonds.
