A mastery of new

Seemingly, the traditions of Preciosa can hardly find use in a new technology. However, the opposite is true. Thanks to many years of experience in the processing of stones, we know that material, precision of work, and the correct handling of light are essential. And we are able to apply the same qualities to synthetic stones as well.

The perfect properties of input raw materials are constantly checked by spectral analysis. In this way we can guarantee the best optical properties of any product. Geometry – such as angles, facets and edges sizes – is optimised using the latest computation aids so that the unique characteristics of synthetic materials – whether it is cubic zirconia, synthetic spinel, or Nanocrystal – are utilized.

For decades, Preciosa has been developing and manufacturing modern equipment of its own for machine cutting and polishing of stones.

Thus it is possible for us to work with synthetic materials and to keep tolerance limits as small as possible. As a result, our products may be used for manual and fully automated setting in without any difficulties.
