Yes, it is, and it's also one of the birthstones for December. Zircon is a naturally-occurring mineral, not to be confused with the synthetic cubic zirconia.
A zircon light is a light produced by incandescent zirconia.
Cubic Zirconia is a synthetic man-made material, while Zircon is a natural substance dug from the earth. Also, real Zircon is more rare and expensive than cz (cubic zirconia), but it's best to take your pieces to a qualified jeweler, as 'site' appraisal of jewelry can be tricky for the consumer if you don't know how to tell the difference (and some appraisers can cheap you as well, one reason to learn about these 'gems' on your own if possible, even take a jewelry course or two.).
A diamond is NEVER made of zircon, they can only be made of carbon.It is trivial for an appraiser to distinguish a cubic zirconia "fake" from a diamond and correctly determine the value.
Depends on what it actually is. If it's a Zircon (Cubic Zirconia), a Spinel or a synthetic Diamond then yes, it is still a gemstone.
Zircon is a colorful gem with high refraction and fire that's often confused with cubic zirconia. Well known for its flashes of multicolored light. It is sometimes looked upon as a cheap Diamond simulant, but in actuality it can be a valuable gem. Its color diversity is caused by traces of certain impurities, some of which are radioactive.
You'd find out what cubic zirconia is conposed of, and compare it to what diamonds are composed of, and since they are composed of different things, their chemical symbols will be different.
Cubic zirconia rings are much less expensive than diamond rings. A cubic zirconia ring may cost around $700 while a diamond ring can cost upwards of $40,000. Cubic zirconia is a much less valuable stone than diamond is and cubic zirconia rings are priced as such.
Only as an impurity, in traces. The correct term is cubic zirconia (ZrO2), not cubic zirconium (Zr).
Minerals are, by definition, naturally occurring. Since cubic zirconia is synthesized in a lab, it is not considered a mineral.
Geologists define minerals as occurring naturally. As cubic zirconia is synthesized in a lab, it is not considered a mineral
Cubic zirconia can be purchased at a variety of offline retailers. Many big-box discount stores such as Target, Wal-Mart, K-Mart, and Kohls carry cubic zirconia jewelry.
