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.

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
