Due to the difference in the type of monitors and other devices, the color in the photo may be different from the real one.
Product group:
Nano Spinel crystal (Nano Gems, Nano ceramic glass) is belongs to the group of glass ceramics with high hardness and almost zero linear expansion characteristics.
Product purpose:
Nano crystal is one of the best imitation of natural colored gemstones, with a unique characteristics.
Gemological characteristics:
Color, luster, hardness and density are very close to many natural stones.
Advantage:
The color is very even and stable at high temperatures, which gives it an advantage in comparison with many natural and synthetic stones.
   
Capabilities:
Optical characteristics makes it possible to imitate transparent. translucent and opaque natural stones.
Our opportunity:
We produce almost all colors and shades of natural stones, which makes it possible to select stones for cutting from 0.7 mm.
