A DiamondAura stone is similar to a Cubic Zirconia, or CZ, stone. The DiamondAura stones are manufactured in a laboratory and are not real diamonds.
DiamondAura stones are of a higher quality than Cubic Zirconia stones. The physical characteristics of these man-made stones rival natural diamonds. For example, DiamondAura stones have a hardness of an 8.5 on the Mohs scale, and natural diamonds have a hardness of 10. Also, the stones have a high refractive index and can cut glass, just as with natural diamonds. To a naked, untrained eye, DiamondAura stones are indistinguishable from true diamond gemstones. Only a trained technician using special equipment can tell the difference.
