Our Cubic Zirconia

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.

Caring for your CZ Jewelry
1. Cubic Zirconia that is set in Karat-gold or Platinum 950 can be worn every day.
2. While almost as hard as diamond, CZ is more brittle. So take precautions, such as removing CZ jewelry when doing heavy work. (Even a diamond can chip if hit a certain way.)
3. Remove your CZ jewelry before showering or cleaning, because soap can leave a sparkle-dimming film. Similarly, remove jewelry when applying makeup and face/body powder, as they can dull its shine.
4. Avoid touching your cubic zirconia stones; the natural oils on your fingers can leave a film that dulls the brilliance.
5. Have your jewelry checked by a jeweler regularly. Your jeweler will check for loose settings and professionally clean the jewelry as well.
Cleaning your CZ jewelry
The more you clean your CZ jewelry, the more spectacular it will look. All jewelry loses its beauty if soap, hand cream, dirt, and body oils collect and solidify on it.
Our Colored Stones
Besides cubic zirconia jewelry, you will find a number of pieces featuring both cz's and simulated emeralds, rubies, sapphires, amethyst and blue topaz as well as the exciting new simulated tanzanite

From the time gemstones were discovered, they were believed to have mystical powers and attributes that could be passed to the wearer. The red of ruby was fiery and passionate; cool blue sapphire was calm and composed. About 2,000 years ago, writers began pairing each of the stones and their attributes with the months of the year and the signs of the Zodiac, and with time, the mythology of birthstones evolved. People were expected to share the attributes of the stone related to their sign of the Zodiac or month of birth.
