Nanosital is a unique material, based on a combination of characteristics: color, luster, purity and the beauty of natural stone, as well as optimal hardness, color stability in wax casting as well as being moderately priced.
Nanosital is an optically transparent polycrystalline material (transparent ceramic) elaborated from glass crystalization.
Nanosital is part of the glass ceramic material  group with multicomponents and high temperature content  created by two important oxides: SiO2 and AI2O3. These oxides are the main components of the most natural stones. Other components are added to achieve ideal nanosital correspondence with its natural analogue.
Nanosital does not contain any health hazardous contaminants (lead, arsenum, cadmin, etc.)
Nanosital provides the opportunity to create almost any color: from natural to decorative.
Nanosital has high stability and batch-to-batch quality consistency.
Nanosital is a registered trade mark in Russia and abroad.
Nanosital is a new jewellery material with similar properties to many natural colored gemstones. It is the best natural analogue imitation today.
Main characteristics of Nanosital
1. Nanosital's specific gravity index is very close to that of the most valuable gemstones such as topaz, sapphire, ruby and aquamarine.
2. Nanosital and the optical properties of the most popular color gemstones are almost similar. Nanosital's  main feature is its lack of an unnaturally strong lustre, which is typical of cubic zirconia, wherein the play of colors remains attractive.
3. Nanosital's hardness (7 on Mohs scale)  guarantees jewellery durability without the loss of its original look. The Nanosital hardness index (7) is higher than glass (5). but lower than one of the hardest materials - corundum (9)
4. Its high melting point allows the use of any colored Nanosital in lost-wax casting.
5. Color and transparency. Its wide color range, full correspondence to natural analogue, perfect optical properties, total transparency, and absence of inner defects makes Nanosital the best, readily available rough jewellery material on the market.
