Main characteristics of Nanosital:
1. Nanosital's specific gravity index is very close to that of the other valuable gemstones such as topaz, sapphire, ruby and aquamarine.
2. Nanosital and the optical properties of the other popular color gemstones are very similar. Nanosital's main feature is its lack of unnaturally strong luster, which is typical of cubic zirconia, allowing the play of colors to remain attractive. It has a refractive index between 1.65 – 1.70 and dispersion of 0.015.
3. Nanosital's hardness (7 on Mohs scale) guarantees jewelry 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. Its wide color range, full correspondence to a natural counterpart, perfect optical properties, total transparency, and absence of inner defects makes Nanosital the best, readily available rough jewelry material on the market.
