To achieve geometrically precise cut of the stones, Preciosa uses a set of computing tools. This results in the STAR effect - an optical phenomenon in the shape of a microscopic eight-pointed star that appears inside the stone as a result of its absolutely precise cut, and can only be seen by means of a special optical instrument. This STAR effect testifies to the highest quality of the stone, its high brilliance, sharp dispersion of light and fire. Preciosa ranks among the leading and most reliable producers who boast this stamp of quality.
Using our special Starscope instrument Preciosa supplies its customers with, you will see this STAR effect in each cubic zirconia stone by Preciosa.
