“LUXcrystal” glowing crystals

Glowing stones “LUXcrystal”


  • Sitall – a crystalline glass-ceramic material on the basis of silicates of alkaline earth metals (MagnesiumCalciumStrontium) in various proportions.

Material’s Uniqueness

We pioneered a unique Sitall, which is:

  • Glowing
  • Has the appearance of semiprecious stones
  • Can be cut and polished

Material’s Technical Specifications

Glowing parameters:

  • Duration: depending on the type from 3 to 20 days, after full recharge:  10 minutes of sunlight reaches the lower threshold of luminosity perceived by human eye level of 0,32 mCd/m2
  • Color of the stones:  ​Yellow, Greenish Yellow, Blue, Green. Various shades.
  • Light color (glowing): ​Blue, Turquoise, Green, Yellow
