What is cubic zirconia jewelry?

Have you ever wondered what, CZ? You have seen CZ engraved on sterling silver jewelry inlaid with colored sparkling crystals. Now, the crystals only what is available for CZ. It means, "Zirconium", the name of the diamond crystals to mimic artificially. In this article, in a word, to know everything that is useful for zirconia crystals.

There are two main divisions of artificial crystals and synthetic simulator. synthetic crystals are generally modeled on the name of natural counterpart. For example, diamonds and synthetic diamonds is almost similar characteristics. On the other hand exercisers, which have different properties, such as natural analogue. These different properties are built, the diamond crystal in its appeal and agree lusture. But again, they have different characteristics. For example, unlike diamonds, crystals of zircon rich in saturated colors. In addition, it is harder than diamond with the same dimensions. Synthetic precious stones such as diamonds artificially same property as the original diamond.

Chemically, CZ cubic crystalline form of zirconium oxide (ZrO2) is. Good to know that there is zirconium, zircon, and it is not. Zircon is the name of zirconium silicate (ZrSiO 4), and other chemicals.

Jewelry industry has long worked to achieve a perfect imitator of the diamond. This study began in 1892 with the discovery of natural mineral water is yellowish monoclinic zirconia. This mineral, known as baddeleyite, slowly found gemologists worldwide attention because of its potential to provide an effective simulator of a diamond. sodium titanate (established 1955), was used yttrium aluminum garnet (YAG) and GGG (gadolinium gallium garnet), which is the predecessor of the simulator. But they were not so promising in the detection of an explosion of diamonds. In 1960, French scientists in the creation of successful crystal CZ, but the crystals are too small to be popular. The final breakthrough was made by Russian scientists in 1970. Basis Bank Skull Russian were viable, as the "cold crucible" of French methods. Shortly after the commercial production world, cubic zirconia began in 1976 they reached the milestone of 50 million carats (10 metric tons) in 1980.

Quality of gems is determined by assessing the color, carat, clarity and cut. The weakening of the color of precious stones, the more valuable it is called. The same is true for crystals CZ. But, of course, can be defined by color lab CZ. The same applies to "clean" appearance. Clarity refers to the number of unwanted penetration of minerals in the gemstone. Nevertheless, crystal CZ often more than a diamond on a scale of clarity, because it is predetermined in the laboratory.

Carat refers to the weight of precious stones. Zircon is always harder than a diamond of the same size as the material is denser than that of diamond. On a scale of rock hardness (Mohs), it has a hardness ranging from 8.5 to 9, compared with 10 real diamonds. CZ has a refractive index of 2.15 to 2.18, slightly lower than 2.417 diamonds.

CZ Jewelry dispersive power greater than diamond. In other words, it will shine brighter than a diamond in certain lighting conditions. This is how diamonds can be cut, but some cut cubic zirconia crystals with different aspects of the same form as diamonds. These tiny differences in the shape aspect can be observed only with a magnifying glass.
