In addition to their core activities Kristall Production Corporation offers manufacturing of polished diamonds on base of the COST+ Program. This means processing of 2ct+ rough from major diamond mining companies. Polished is produced under any requirements by the customer's request, including Triple Excellent or fancy cuts. The manufacturing process takes about 2 months depending on the category of rough and amount of polished for production. In the process of creating a perfect polished diamond, Kristall uses state-of-the-art equipment and techniques, including those developed within the company. Sophisticated CAD-control systems are used to ensure that all the elements of a diamond, each facet and angle strictly conform to most demanding requirements.
