“LUXcrystal” glowing crystals
Glowing stones “LUXcrystal”
Material
- Sitall – a crystalline glass-ceramic material on the basis of silicates of alkaline earth metals (Magnesium, Calcium, Strontium) in various proportions.

We pioneered a unique Sitall, which is:
- Glowing
- Has the appearance of semiprecious stones
- Can be cut and polished
