Education
The CZ story began in 1937, when the cubic form of zirconium oxide (CZ for short), was discovered by two German mineralogists. It wasn't until the 1970"s however - when Soviet scientists learned how to "grow" this mineral in a laboratory - that it became popular with jewelry designers. Gemologists agree that Cubic Zirconia is the finest diamond simulant because it comes closer than any other gem material to matching the characteristics of a diamond. Most people, even trained gemologists, cannot tell the difference with the naked eye.
Almost all the cubic zirconia rough in the market, today, is chemically comprised of zirconium oxide and yttrium oxide. Individually, both of these materials are opaque, white ores, but when they're melted together under appropriate conditions, they combine to form an amazingly brilliant, clear crystal.
Producing fine cubic zirconia is an art in itself. The extremely high temperature required to melt the ores (almost 5,000 degrees Fahrenheit) is too hot for any conventional crucible, or melting vessel, to withstand. Therefore, to produce cubic zirconia, a "skull crucible" system is used, where the melting zirconia powder actually creates the sides of its own container during its manufacture.
Cooling this extremely hot molten ore is the most crucial step in the entire process. A carefully programmed cooling procedure is needed to form the flawless crystals that become cubic zirconia gemstones.
Like diamonds, the best cubic zirconia are colorless (or white) and don't lose their brilliance. Given proper cleaning, the cubic zirconia will retain its beauty for years.
If you do happen to chip or scratch it, it's only a few dollars to replace the stone with a new one.
To fill the need for colors, manufacturers also produce a variety of colored cubic zirconia.
Cubic zirconia are cut in the same way diamonds are. The size of the gemstone is usually indicated by its weight in carats, a carat being one-fifth (1/5) of a gram. The stone can also be measured in millimeter diameter size.
Because the cubic zirconia stone is so dense and solid, it outweighs a diamond of the same millimeter size, weighing 1.7 times more than a diamond of the same millimeter diameter. When we talk about carat weight to describe a CZ, we use the diamond equivalent weight or the diameter of the stone in milimeters.
The best cleaning agent for cubic zirconia is liquid dishwashing detergent. But, other cleaners can be used, preferably those without ammonia. Natural skin oils, soap,
and dirt cause a film that dulls the beauty and luster of the cubic zirconia, just as it dulls real diamonds.
A cubic zirconia is as hard as a good sapphire coming in at 8.5 on the MOHS hardness scale.
