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. Zircon can make a very attractive and affordable gemstone.

Zircon is zirconium silicate, belonging to the group of nesosilicates. Origin of name: from Arabic zarqun and Persian zar = gold, gun = colour. Zircon is a natural forming mineral and it is not related to the synthetic diamond substitute Cubic Zirconium which is created in a laboratory.

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.

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.

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.

It contains zirconium, silicon and oxygen with small quantities of rare earths and radioactive elements such as thorium and uranium. It is used widely in industry as the main source for the metal zirconium used in steel alloys, abrasives and jet engines. It is not connected to Cubic Zirconia.

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, which is used as a carbon raiser in the steel industry (Earth Metrics, 1989).

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. The natural colors are yellow, brown, red and green.

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).

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. Diamonds in classic shapes are also used to adorn men's engagement rings.

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. Colloidal Gold may also be added.

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. It has been said that this stone helps to protect against nightmares, eases pain in childbirth, and improves endurance.

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. It is found in igneous rocks (as primary crystallization products), in metamorphic rocks and in sedimentary rocks (as detrital grains).

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.
Cable Chain
Metal ovals are strung together in a rotating pattern to create this chain.

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.

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. These elements make Eudialyte a main interest as an individual’s part of their collection.

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.

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."
This crystal is known specimen No. 4. (See G. R. Rossman's Caltech website for more details.) ...

A natural gemstone, which occurs in various colors; zircon is found in many Asian countries, notably Cambodia and Sri Lanka as well as in Brazil, Australia and East Africa. Colorless when pure, zirconium silicate takes on various shades due to impurities.

Dichroic coated glass transmits some wavelengths of light and reflects others, giving it a distinctive metallic appearance. The glass is coated with a very thin metal film, such as aluminum, chromium, silicon, zirconium, colloidal gold or the metal alloy titanium, ...

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 zirconium oxide. It tends to chip or turn yellow over time.

Cubic Zirconia: Rare in natural occurrence, 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: zirconium oxide; ...

adornment for wedding and engagement rings, but they are by no means the only option.
