What is CZ Cubic Zirconia?
CZ Cubic Zirconia Properties Uses Meaning and Varieties. The world’s most famous diamond stand in, cubic zirconia is the crystalline form of zirconium dioxide. Colorless, optically flawless and nearly as hard as diamonds, cubic zirconia gems are created under exacting conditions in the laboratory and grown into perfect cube-shaped columnar crystals. Loose CZ diamonds are carefully cut in the same manner as natural diamonds and can be cut into the same wide variety of attractive and fancy shapes and sizes.
CZ Cubic Zirconia Properties
Cubic zirconia diamonds are so visually identical to natural diamonds that it can be impossible to tell the difference without a professional inspection. One of the unique attributes of cubic zirconia is its ability to be perfectly created in the most sought after colors of other crystal gemstones, allowing lab creation of beautiful CZ emeralds, cz topaz, CZ Amethyst, CZ aquamarine and many other glittering gems. Its same appearance from naturally created gems, durable hardness, and low cost have made loose cubic zirconia the most exciting and important diamond competitor in the jewelry and fashion marketplace. Jewelers have been substituting other materials for diamonds and precious gems for centuries in an attempt to find affordable alternatives to expensive natural gems.
Varieties and Uses of CZ Cubic Zirconia
Ancient Egyptians painted wooden gems on the coffins of royalty. In the 18th century, Europeans wore paste jewels made from carefully cut and polished leaded glass. Today some fraudulent foreign gem dealers place carefully molded silvered or colored foil paper behind set diamonds and pearls to give greater brilliance and deeper colors to inferior stones.
Synthesis of CZ Cubic Zirconia
The successful laboratory synthesis of high-quality, jewelry-grade loose cubic zirconia in 1976 began with a search for an economical substitute for diamonds for use in optical lasers. Since the 1892 discovery of baddeleyite, the rare natural form of zirconium oxide, zirconia’s extremely high melting point had presented a considerable obstacle to commercial production. With a melting temperature of nearly 5000 degrees Fahrenheit, existing crucibles could not hold the mineral in its molten state.
It would be nearly a century after the discovery of baddeleyite before scientific knowledge and technology would reach a point that would allow successful laboratory creation of cubic zirconia. Tune into our next post for the rest of the story.
