FAQ-Product Informations:
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).
Dispersion:
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.
Refractive index:G> CZ has a refractive index of 2.176, compared to a diamonds 2.417.
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.
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 CZ stones 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. Also as with diamonds, the skill of the stone cutter makes all the difference. Stone cutters do much more than cut. They analyze the stone carefully to determine how much of the stone should be cut off to give proper clarity. Then, they take many steps to perfect their cut without taking away from the stone.
Though the Brilliant cut is the standard, there are other popular cuts such as the Trillion, Princess, and Radiant cuts. There are also a variety of shapes to give each stone its own unique personality.
