Nano Crystal

The best substitute for natural gems

What are NANO Crystal stones?

Nanogem – is the glass-ceramic material with nano sized (10⁻⁹m) crystals of Spinel in an aluminosilicate glass matrix, which is not special glass and it is not synthetic crystal or mineral – it is their hybrid. This composite material has unique physical and optical properties: Color (homogeneous and even), Density (3-3.3g/cm³), Luster (RI=1.61-1.64); Melting temperature (more than 1650 C°), and high thermal shock resistance make this material ideally compatible with the wax-casting technology. Thanks to these properties, all produced types of stones — transparent, translucent, and opaque ones completely replicate Brightness, Color, and Density of gemstones — in more than 350 colors and shades available: Emerald, Sapphire, Ruby, Garnet, Topaz, Aquamarine, Amethyst, Morganite, Kunzite, Peridot, Tsavorite, Rubellite, Red and Black Spinel, Turquoise and many others.

Why Nanogem is the best imitation gemstones compared to other materials?

Colored glass usually has low hardness and insufficient luster. If compared with CZ, Hydrothermal quartz, Synthetic corundum, Spinel, etc. The material is more uniform in color and is very close to the natural gems in hardness, refractive index, and luster. Moreover, unlike glass and many synthetic stones, Nanogem does not change color or destroyed during casting with stones.
​Recently, a lot of color materials with the prefix “nano” appeared on the market. Some of them claim that their material is also glass-ceramic, but in fact, almost all of these materials are just conventional colored glass, sometimes zirconium or yttrium, but still Glass. No nanocrystals in these materials can be traced. Accordingly, there are no comparable properties with our Nanogram.

There are more than 100 colors for the Nano stones:
1.Nano gemstone can simulate the colors of many kinds of precious and semi-precious gemstones in the market.
2. High temperature-heat-resistant: (more than 1650 C°) and high thermal shock resistance makes this material ideally compatible with the wax-casting technology.
