Most competitive price,best design and qualitywill be provided.Cubic zirconia versus diamond:There are a few key features of cubic zirconia which distinguish it from diamond:One face of an uncut octahedral diamond, showing trigons (of positive and negative relief) formed by naturalchemical etchingHardness: cubic zirconia has a rating of approximately 8 onMohs hardness scalevs. a rating of 10 for diamond.[1]Specific gravity: the density of cubic zirconia is about 1.7 times that of diamond.Refractive index: cubic zirconia has a refractive index of 2.15-2.18, compared to a diamond's 2.42.Dispersionis very high at 0.058-0.066, exceeding a diamond's 0.044.Cut: cubic zirconia gemstones may be cut differently from diamonds. The facet edges can be rounded or "smooth".Color: only the rarest of diamonds are truly colorless, most having a tinge of yellow or brown to some extent. By comparison, a cubic zirconia is often entirely colorless: equivalent to a perfect "D" ondiamond's colorgrading scale. Other desirable colors of cubic zirconia can be produced including near colorless, yellow, pink, purple, green, and even multicolored.Thermal conductivity: Cubic zirconia is a thermal insulator whereas diamond is a very good thermal conductorCubic zirconia(CZ) is the cubic crystalline form ofzirconium dioxide(ZrO2). The synthesized material is hard, optically flawless and usually colorless, but may be made in a variety of different colors. It should not be confused withzircon, which is azirconium silicate(ZrSiO4). It is sometimes erroneously called "cubic zirconium".Because of its low cost, durability, and close visual likeness todiamond, synthetic cubic zirconia has remained the mostgemologicallyand economically important competitor for diamonds since commercial production began in 1976. Its main competitor as a syntheticgemstoneis a more recently cultivated material, syntheticmoissanite
