We deal in rough diamonds—diamonds that are completely untouched by a polishing wheel. They typically enter the market in a large, sealed parcel from one particular mining company. As nature would have it, rough diamonds come in all shapes and sizes, as well as colors and purities. The larger, whiter and cleaner the diamond, the rarer it is. Their very shape tells of their natural origin. Although they can have multiple shapes, they usually have an octahedron-like appearance.
We trade in all types and sizes of diamonds from +1ct and above. We also deal in all kinds of rough stones like Sawables, Makeables, Flats and Cleavages.
We always organize our parcels into tailor-made solutions for polishing factories worldwide. Our business has a global reach that is measured via the trading of millions of carats per year. And yet, our core principles remain very personal—to offer extraordinary services with flexible, customized solutions to help our clients achieve their goals. All diamonds fully comply with all requirements specified on the Kimberly Process Certification Scheme.
The aesthetics of diamonds depend on visual properties such as high refractive index, color dispersion, luster and a high degree of clarity. Better the Polish, brighter and more lustrous the stone to be created. A team of skilled and dedicated artisans transforms each rough stone into a majestic and brilliant cut of a diamond. We manufacture polished diamonds from Melee and above from IF to SI2 that mainly focus on four C’s: cut, clarity, color and carat weight. We make a wide variety of fancy shapes.
