The secret of manufacturing high-quality polished diamonds is encouraged by a proprietary system of quality control, which in course of time, achieved true perfection.

In the course of grading, the principle parameters of a polished diamond are determined: the weight, colour, clarity and polish, depending on which the final characteristic of the stone – the price – is calculated.

Having obtained this final characteristic, the polished diamond changes over from the category of an object for processing to the category of a final product, merchandise subject to sale.

In spite of all the technological progress, automation, computer-aided- and laser technologies, nothing can substitute the knowledge, experience, and inspiration of a craftsman. The specialists of Kristall are deeply convinced that the key to the diamond making will always be in the human factor.
