Loose Nano crystal Yellow Sapphire Color 2mm Round Faceted 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.

Loose Cubic Zirconia Amethyst Triangle shape Triangular faceted Brilliant cut 4x4mm gemstones wholesale from China Manufacturer and Suppliers Pictures What's Triangle Cut Gemstones? With three straight or slightly curved sides, preferably of equal length, the Triangular Brilliant Cut is a generic term for a shape that today also is referred to as the Trillion, Trilliant and sometime the Trill. The design of the cut is generally credited to the Asscher brothers in Amsterdam, and the term “Trilliant” was trademarked by the Henry Meyer Diamond Company of New York in 1962, to underline the brilliance of the triangular cut. Its patent has since expired, meaning that the various terms are now widely used to refer to most faceted triangular shaped stones, although not to the step-cut tapered baguette. Triangular Brilliants are most often produced from flattened, triangular rough diamonds called macles. Most often they are smaller in size and are used, generally in pairs, as side stones to complement larger solitaires, or in diamond-stud earrings. Larger stones can be used as centerpieces in jewelry. What is Cubic Zirconia? A: Cubic Zirconia (or CZ) is zirconium oxide (ZrO2 ), is widely synthesized for use as a diamond simulant and it is a lab made created stone with a specific gravity of between 5.6-6.00 and at about 8.5 hardness on Mohs scale, which is harder than most #natural gemstones#. Its refractive index is high at 2.15 - 2.18 (B-G interval) and its luster is very good. Its dispersion is very high at 0.058 - 0.066, exceeding that of diamond (0.044). #Cubic Zirconia Gemstones# is the best stimulant for the Real diamond, it's beautiful and brilliant for the Jewelry designs.
