WHAT IS NANOSITAL (SITALL)?

green stone jewelry earrings made in russia emerald alternativeNanosital, or sitall, is a unique material consisting of the main components of natural jewelry stones - SiO2 and Al2O3, with the only difference that it was synthesized in the laboratory. Thus, scientists create real miracles, folding their hands with various combinations of these oxides! It turns out a kind of jewelry "puzzle", repeating the natural minerals for all the chemical and physical parameters. According to its properties, the sital is the closest to natural topaz. Crystal transparency and a wide range of possible colors give an unprecedented opportunity to recreate almost all colored semiprecious and even precious stones.

From official website:

"Nanosital is an optically transparent polycristalline material that is formed by the crystallization of glass with corresponding chemical composition and has higher physical and chemical properties than the original glass.

Nanosital is one of glass-ceramic materials, which are known for more than 50 years and have a wide range of compositions and applications. RusGems has adapted existing technology to create a material specifically optimized for jewellery. As a result a multi-component high temperature composition on the base of two main oxides – SiO2 and Al2O3 – was obtained. It is well-known that the above-mentioned oxides are key components of most natural gemstones. The rest of nanosital's components are picked to approximate the maximum required optical characteristics as well as density and hardness. Our technology allows us to vary components of composition quite widely. As a result nanosital that is absolutely identical to its natural counterpart can be produced each time."

Nanosital does not contain any health hazardous contaminants (lead, arsenum, cadmium, etc.).

It was originally manufactured in the former Soviet Union and was used in the making of primary mirrors for the Russian Maksutov telescopes.
