A:There are four main factors that help determine the quality or grade of cubic zirconia. These are carat (or carat weight), clarity, color, and cut. CZ stones are imitation diamonds or simulants and are measured in carat weight. Loose cubic zirconia stones are always heavier than real diamonds. This is because the materials that are used to create the stones are denser. Though loose cubic zirconia stones are generally colorless, many shades of colors can be added using trace elements during the manufacturing process. These colors might include lavender, peridot, pink, violet, champagne, aqua, citrine yellow, and others. Typically, transparent cubic zirconia will be the more valuable, high-end diamond imitation.Colored CZstones are valued according to the rarity, evenness, and tone of their colors. Clarity, or clearness, of loose cubic zirconia is also a quality factor. The manufacturing process can sometimes cloud a stone, making visible imperfections. Just as with genuine diamonds, the clearer the stone is, the greater the value. The cut is also very important in determining quality for loose cubic zirconia stones. Just as with diamonds, the cut reveals the stone's beauty through every facet. The facets must be even and precise to create just the right appearance....

A:Synthetic gemstones are grown in a laboratory instead of being formed in the ground by nature. They are physically and chemically identical to natural-grown gems but cost much less to produce and to buy. Just like natural gems, synthetics vary tremendously in quality and it takes several months to create a batch of gems. Using low-quality processes, synthetic sapphires and rubies can be created for less than a dollar a carat, whereas high-quality synthetics can cost a hundred times more to create and sell for several hundred dollars a carat at retail.

A:CZ is the abbreviation for the word cubic zirconia. Simulated diamonds and cubic zirconia are the same thing. Cubic Zirconia is undoubtedly the best diamond simulate available today. Cubic Zirconia has successfully established itself as the high quality and affordable diamond substitute in today's fashionable jewelry market. The untrained and naked eye cannot distinguish the difference between a real diamond and Cubic Zirconia. Even gemologists cannot tell the difference unless various testing and examination is done. Cubic Zirconia is an incredible hard material similar that of a real diamond and with the introduction of color, it has great potential as a gem to fulfill elegant fashion demand at a fraction of the cost. The composition of this man made product is typically a combination of Zirconium Oxide and Yttrium Oxide both of which are opaque by nature. But when melted together under intense heat reaching almost 5,000 degrees Fahrenheit and then cooled under controlled conditions, they produce what we call Cubic Zirconia. Cubic Zirconia is colorless in its pure state. The various colors are achieved by mixing in small quantities of chemical additives.

A:Cubic zirconia (CZ) is so optically close to diamond that only a trained eye can easily differentiate the two. There are a few keyfeatures of CZ which distinguish it from diamond, some observable only under the microscope or loupe. For example: Dispersion: With a dispersive power greater than diamond (0.066 vs. 0.044) the more prismatic fire of CZ can be seen by even an untrained eye. Hardness:CZ has an 8.5 on the Mohs Hardness Scale vs. a rating of 10 for diamonds. Meaning CZ can only be scratched by sapphires or diamonds. Specific gravity:CZs are heavyweights in comparison to diamonds; a CZ will weigh about 1.7 times more than a diamond of equivalentsize. Obviously, this difference is only useful when examining loose stones. Flaws:Contemporary production ofcubic zirconiais virtually flawless. Whereas most diamonds have some sort of defect, be it a feather, included crystal, or perhaps a remnant of an original crystal face (e.g. trigons). Refractive index:G> CZ has a refractive index of 2.176, compared to a diamonds 2.417.

A:Cubic Zirconia(or CZ) is zirconium oxide (ZrO2 ), is widely synthesized for use as a diamond simulant and it is a lab made created stone with a specific gravity of between 5.6-6.00 and at about 8.5 hardness on Mohs scale, which is harder than most natural gems. Its refractive index is high at 2.15 - 2.18 (B-G interval) and its luster is very good. Its dispersion is very high at 0.058 - 0.066, exceeding that of diamond (0.044).
