Zirconium Oxide, or more accurately Zirconium Dioxide, also called zirconia, when crystallised in cubic system, it is known as Cubic Zirconia, the most successful imitation diamond.
Cubic is also used as drops. White gold drop earrings set with cubic ; white gold earrings long tube drop design set with cubic are also available in the market.
Zircon (zirconium silicate) is a common mineral that belongings to the group of nesosilicates, or basic silicate rock-forming minerals.
ZrSiO4, Silicate. Zircon is not the same material as the artificial gem material Cubic Zirconia (or CZ). Zircon resembles diamond in luster and fire and colorless zircons have been mistaken for diamonds by experienced jewelers.

This cubic replica was designed and cut by Scott Sucher. Sucher said he had to use mathematics to figure out the angles and measurements of the sides of the stone because of a lack of information about it. ...

Available in a wide variety of beautiful colors, cubic zirconias are synthetic (manmade) gemstones.
A silicate of , this mineral occurs in different colours or may be colourless, the latter often being referred to as the poor man's diamond. In fact, zircon tends to be rather dim and is only used for inexpensive jewelry.
In addition to zirconium, silicon and oxygen, zircon contains small quantities of rare earths and radioactive elements such as thorium and uranium. These inclusions give zircon differents hardnesses and properties.

CZ denotes cubic zirconium, a widely used simulant, an imitation for a natural gemstone including diamond. But CZ is easily detectable by it's 80% higher weight than a normal stone of the same proportions or by thermal conductivity testing.
Zircon, Zirconia, Minerals
The minerals zircon, baddeleyite and zirconolite are a close family.
Minerals of the Earth's Surface
The thousands of minerals known in rocks become a mere handful at the Earth's surface.
Cubic Zirconia is formed through a complicated process from zirconium oxide and yttrium oxide. these two chemicals are melted together at almost 5000 degrees fahrenheit, and then carefully cooled to create flawless crystals.
A Cubic is not as hard as a diamond (7.5 to 8.5 on the Mohs scale vs. 10 for a diamond) and will show wear on the facet edges with routine wear. CZ is about 75% heavier than diamond.
Almost all the rough CZ's in the market are composed of zirconium oxide and yttrium oxide, both of which are naturally white but combine to form a brilliant clear crystal.
In that process graphite is ground to a fine powder for use as a slurry in oil drilling; in silicate, sodium silicate and isopropyl alcohol coatings for foundry molds; and for calcined petroleum coke, ...
Cubic Zirconia (or CZ) is the cubic crystalline form of zirconium dioxide (ZrO2). The synthesized material is hard, optically flawless and usually colourless, but may be made in a variety of different colours.
Pink Ice, a term created by television shopping networks, is actually pink cubic , a synthetic gemstone. Pink Ice has become very widely accepted as Octobers birthstone and can be found in many jewelry stores today.
Zirconium is the connecting element in zircon [ZrSiO4]. Aluminum takes the role in the aluminosilicate group (staurolite, topaz, and the polymorphic Al2SiO5 gems andalusite, kyanite, and sillimanite).
Almost all the cubic zirconia in the market today is chemically comprised of oxide and yttrium oxide.
A glass which contains ultra-thin layers of aluminum, chromium, silicon, zirconium or the metal alloy titanium. The colors are almost holographic in appearance. Addition of the various elements is what produces the bold and dramatic colors.
Zircon is silicate and Cubic Zirconia is a form of dioxide.
Metaphysical/Medical properties: The zircon is known as a stone of virtue.
Gemstones of mineral Zirconium silicate with traces of uranium. In colors from transparent, yellow, brown, green, blue green, blue and red. Have high optical properties.

Chemical composition -- oxide plus yttrium or calcium.
Color -- Colorless when pure, but many different colors are provided by small chemical additives..
Optics -- R.I. 2.15-2.18 (singly refractive). Dispersion .058-.066.
Its chemical name is zirconium silicate. Zircon is a remarkable mineral, if only for its almost ubiquitous presence in the crust of Earth.
Eudialyte is mostly used as a small part of . Another usage of Eudialyte is as a minor stone, but this use is restricted due to its rarity, which is multifaceted by its reduced crystal habit.
ZIRCON A genuine and natural gemstone not to be confused with Cubic Zirconium, which is a synthetic. Zircon is common in colorless, blue and pink or rose varieties. Colorless Zircon was used as a Diamond simulant until Cubic Zirconia came along.
Cubic zirconia is a man-made compound of , oxygen and yttrium, which was discovered in 1937. It lacks the silicon of a true zircon, and is, of course, very much younger.
Stands for cubic zirconia, the cubic crystalline form of zirconium dioxide. This synthetic stone can be produced in colors, is rated 8 on the Mohs Hardness Scale, and is nearly refractive as a diamond.

Synonyms are "fianite," "phianite," and "CSZ" (cubic stabilized zirconium oxide). Zirconias have been manufactured in a wide range of sizes and shapes since 1977. Some zirconias have even been made with artificial inclusions.
Cubic zirconia: One of the most common and popular diamond simulants is the cubic zirconia. Created in a laboratory, cubic zirconia is a cubic form of oxide. It tends to chip or turn yellow over time.
I sent the crystal fragment to my good friend at Caltech, Dr. George Rossman. He played with me regarding the ID until I begged him. His reply was clever. "You have calcium zirconium and boron here." ...
CZ has been synthetically produced in volume and multiple colors since the 1970's. To the untrained eye, white CZ appears as a high-quality diamond, though it is 75% heavier, has more "fire" and is softer than diamond. Composition: ...
