The cost of precious gems exceeds the means of many people who enjoy wearing jewelry. For centuries, science has sought convincing substitutes for natural stones. While "faux" stones cannot pass examination by trained professionals, some have gained popularity in their own right.
Cubic Zirconia
Cubic zirconia is zirconium dioxide in cubic crystalline form. Its density and lack of optical flaws make it an inexpensive synthetic substitute for diamonds. Manufacturers of cubic zirconia can produce yellow, orange, red, green, purple, pink or brown gems by adding traces of various metal oxides.
Diamonique
Founded in 1986, the Pennsylvania-based Quality Value Convenience (QVC) television shopping channel markets products to consumers through live product demonstrations and direct telephone purchases. On October 8, 1988, QVC acquired the technology and brand rights to Diamonique from MSB Industries, Inc. In protecting its trademark against infringement, QVC has disclosed that Diamonique is a trade name for cubic zirconia.
