Cubic Zirconium
Cubic zirconium (also known as cubic zirconia) is an inexpensive, lab-produced gemstone that resembles a diamond. Cubic zirconia was developed in 1977.

Cubic zirconium (also known as cubic zirconia) is an inexpensive, lab-produced gemstone that resembles a diamond. Cubic zirconia was developed in 1977.

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 zirconium is also used as drops. White gold drop earrings set with cubic zirconium; white gold earrings long tube drop design set with cubic zirconium 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, Zirconium 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 zirconium 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. ...

aka CZ, cubic zirconium, Diamonique (brand name), Fianit, synthetic diamonds
Available in a wide variety of beautiful colors, cubic zirconias are synthetic (manmade) gemstones.

A silicate of zirconium, 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, Zirconium Minerals
The zirconium 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.

CZs are made of the chemical zirconium oxide (ZrO2) and can be cut, faceted and polished like all gemstones. CZs have a very high refractive index which is the property that allows them to reflect a lot of light in a manner similar to a diamond.

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 Zirconium 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 zirconium 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 zirconium, a synthetic gemstone. Pink Ice has become very widely accepted as Octobers birthstone and can be found in many jewelry stores today.

zircon - An important gem stone, a zirconium silicate. It is characterized by very high refractive indices, about 1.93 and 1.99. Hardness, 7 1/4-7 1/2; specific gravity, 4.68. It has high dispersion and well-cut stones have a good fire.

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 zirconium oxide and yttrium oxide.

Rather, they are set with small diamonds or cubic zirconium. Diamonds set into the band or set within the centre of the ring itself (in channel setting) are less prone to damage making it a practical choice.

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 zirconium silicate and Cubic Zirconia is a form of zirconium 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.
Hardness : 6.5-7.5 Refractive Index : 1.70-1.706 Density : 3.25-3.37 ...

Chemical composition -- Zirconium 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 zirconium. 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 zirconium, oxygen and yttrium, which was discovered in 1937. It lacks the silicon of a true zircon, and is, of course, very much younger.
