Loose Nano Crystal and Nanosital gemstones wholesale from china supplier and manufacturer.
What is Nano Gemstones ?
A: Nanosital or Nano Crystal gemstone - 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.
Nanosital or Nano Crystal gemstone are a new type of created gemstone made especially for jewellery. The colour is homogeneous, meaning that if you bought 100 emerald green nano crystal stones, the colour would be exactly the same in every stone. The material has been created with precious metal clay in mind, so any size gem should be kiln safe and blow torch safe with out colour change or damage.
Nanosital or Nano Crystal gemstone does not contain any health hazardous contaminants (lead, arsenum, cadmium)
Hardness: 7 on Mohs scale
Refractive Index: 1.65-1.7
Specific Gravity: 3.5-4
Dispersion: 0.015
Melting Point: 1700 degrees Celcius
It does not change color when heated. Can be used in wax casting.
The Main characteristics of Nanosital/Nano Crystal stones:
1.Nano Stone's specific gravity index is very close to that of the most valuable gemstones such as topaz, sapphire, ruby and aquamarine.
2.Nano Stone and the optical properties of the most popular color gemstones are almost similar. Nano Stone'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.Nano Stone'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 Nano Stone 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 Nano Stone one of the best, readily available rough jewellery material on the market.
Why Nano Gemstone is one of 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 in the market. Some of them claim that their material is also a 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 Nano gemstones.
