Loose nano crystal Emerald Green #113 Color Round Shape Faceted Cut 3mm gemstones wholesale from china supplier and manufacturer. Pictures What is Nano Gemstones ? A: 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. 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. #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...
