Genuine Briolite does not scrath like cubic zirconia, nor does it fog up when you breathe on it. The reason for it is this: SYNTHETIC GEMSTONES are identical to a natural gemstone in almost every way. This includes the same basic crystal structure, refractive index, specific gravity, chemical composition, colours, and other characteristics. Since the same gemological tests are used for stone identification on both natural and synthetic gems, it is sometimes even possible for a gemologist to be puzzled as to whether or not a stone is natural or synthetic. When this occurs, the best course of action is to send the stone to an accredited gem laboratory, like the Gemological Institute of America. They can positively determine whether a stone is synthetic or naturally occuring. Only minor internal characteristics allow separation of a synthetic gemstone from a natural gemstone. IMITATION GEMSTONES merely imitate the color or look of a natural stone. They can be made out of anything. A Cubic Zirconia or Moissanite are IMITATION diamonds, for example. A blue piece of glass could be an imitation sapphire. A variety of blue synthetic forsterite is an excellent imitation for tanzanite, while chemically, it's composition is much closer to the yellowish green peridot. Another classic example is the "alexandrite" set in many jewelry pieces is actually a variety of vanadium colored synthetic sapphire!

Are Cubic Zirconia rings expensive?
That would depend greatly on your idea of expensive. They are not as expensive as higher quality and rarer stones like diamonds and emeralds. Typically, cubic zirconias are a less expensive choice than diamonds and are sustituted for such.
What synthetic minerals have been developed as a substitutes for diamonds?
Synthetic diamonds have been created as substitutes for natural diamonds in materials where hardness and cutting ability is strongly desired. Definitions are in order: SYNTHETIC - like Dolly the sheep, a synthetic is real and exactly the same as a natural gem with one exception. It was created in a lab and not naturally occuring and recovered from the earth. At this date, most jewelers even using all the best test cannot tell the difference between man made diamonds and natural diamonds without expensive and costly equipment. A simple pen sized diamond tester can instantly let you know a cubic zirconia is not real. Additionally Cubic zirconia of the same dimensions weigh much more than diamonds. Cubic zirconia can be scratched by a diamond but a diamond cannot be scratched by a cubic zirconia. If you met the woman who was the first test tube baby born in the 1970's, she is a "synthetic". A blow up doll is a "simulant". SIMULANT - a substitute that is a completely different substance not like the natural and not like the Synthetic. There was once a puppet on TV called Lamb Chop. It is meant to represent a sheep but it is not real. Cubic Zirconia is a man made gem that can fool many people but is not a diamond. To answer the questions all diamond synthetics are made of carbon, pure carbon just like a natural diamond. For simulants the materials they may be made from are varied from glass to moissanite to cubic zirconia.
Does zirconium cut glass?
The metallic element Zirconium (Zr) has a Moh's hardness of 5.0, this is not hard enough to cut glass. The crystalline compound Zircon (zirconium silicate ZrSiO4) has a Moh's hardness of 7.5 7.5 is harder than Quartz and therefore Zircon will scratch glass. The crystalline compound Zirconium dioxide (ZrO2), sometimes known as zirconia (the one that looks like diamond) has a Moh's hardness of 8-8.5. This too will scratch glass.
How do grams per cubic meter look?
You meant grams per cubic meter squared. And it looks like this: G/Cm3Cm= cubic meter not centimeters.
Why would you measure a pool in cubic feet?
You are free to measure the pool with any units of volume that you like, it doesn't have to be cubic feet.
Which looks more like the real thing, cubic zirconia or rhinestones ?
Cubic zirconia more closely resembles diamonds than rhinestones. Cubic zirconia are hard, durable and can't be distinguished unless under a trained eye of jewelry professional.
What is cubic zirconia?
* A man-made substitute for diamonds. It is much closer to the physical characteristics of a real diamond than other imitations. * Cubic zirconia (also known simply as 'cz') is the finest available alternative to a diamond. This is because it has many of the properties of a diamond. It has the same shape and colour and, like a diamond, cannot be scratched by dirt or sand. Most people, even trained gemmologists, cannot tell the difference between a well-cut cubic zirconia stone and a diamond using only the naked eye. There are, however, differences between diamonds and cubic zirconia. Although in appearance cubic zirconia looks just like a good quality diamond, it is more dense than a diamond - weighing up to 60% more than a diamond of the same size. In addition, it is of note that cubic zirconia is a man made crystal. If, therefore, a piece of cubic zirconia is not perfect, it is discarded. Only the highest grade and most beautifully polished cubic zirconia stones are used throughout our silver jewellery collection. We believe that cubic zirconia is not merely a diamond substitute but a beautiful semi-precious gem in its own right. Given proper cleaning, cubic zirconia will retain its beauty and brilliance for years. Cubic zirconia jewellery can be cleaned easily using hot soapy water or warm water with a small amount of dishwashing detergent. It might help to first remove any dirt with an old toothbrush.
Where are the typical costs of a cubic zirconia bracelet?
Cubic Zirconia isn't very expensive, although it looks like a real diamond/ crystal. It has a typical value of ‘£20 per every few "carats", although whoever the retailer is, the price does vary.
What is the proper way to clean a cubic Zirconia necklace?
There are a couple proper ways to clean a cubic zirconia necklace or other piece of jewelry. One way is to take it to any jewelry store and have it steam cleaned. The other is to apply jewelry cleaning solution to a soft brush like a toothbrush and brush gently. In the mean time, cubic zirconia jewelry should be kept away from corrosive substances such as swimming pool chlorine and acidic cleaning products.
Where might one go online to purchase Cubic Zirconia Stud Earrings?
Cubic Zirconia stud earrings can be found in most inexpensive jewellers such as Warren James, F Hinds and branches of Argos. They can also be found in department stores, on catalogue sites like Very and Littlewoods, and online on Amazon.
What is a diamonultra diamond?
"DiamonUltra™ Cubic zirconia is a man-made stone that is chemically different from a diamond, yet looks very much like the real thing. An alloy of zirconium oxide and usually yttrium oxide, cubic zirconia made its mass-market debut in the 1980's as an inexpensive diamond substitute."

Is a 925 dl bracelet expensive?
925 Means real silver DL means Diamond Like..so probably Cubic Zirconia stones. So..not really expensive.
What are black diamonds and where can I find them?
Black diamonds are a form of diamond, however, they are black in color. They can also be made synthetically, like a cubic zirconia can. They are readily available at many jewelry stores.

How do you tell a real diamond from a fake?
Well, if you're not a gem expert you will not be able to tell the cut and the clarity of the stone or even if its real. You can take it to a place that sells gemstones or even a pawn shop. They can tell you with a diamond tester if it is real or not: you can't tell if its real or not by looking at the metal band.Reputable jewelers will offer a certificate of authenticity. Quality diamonds sparkle like nothing else in the world. You can even go to someplace like Sears and have them show you the difference between a diamond and a cubic zirconium.An x-ray crystallograph can provide a reasonably high degree of assurance when it is used to identify smaller diamonds that were cut from a larger one. A cheap way to test a questionable gem is to drop it into clear mineral oil. A real diamond will remain visible because it has an optical density that is higher than (most) fakes and higher than the oil.The best way is to take it to a certified gemologist for an appraisal.A Few Simple Tests:Heft test (weight compared to size):A diamond with the same size of a "synthetic cubic zirconia" will be lighter in weight (carat).Hardness Test:Diamond can scratch "synthetic cubic zirconia" easily while "synthetic cubic zirconia" can't scratch diamond. This destructive test is not recommended but if required use apply on or below girdle area of stone.Read through effect:RBC (round brilliant cut) diamond when placed table down on written matter (generally a line or point is enough) and viewed from above the girdle (pavilion facets) will not exhibit read through effect whereas "synthetic cubic zirconia" will exhibit low read through effect.Inclusions:Some diamonds will have visible inclusions whereas synthetics, especially cubic zirconia will have white unmelted powder which sometime looks like gas bubbles.
What does this marking mean on my heart necklace dqcz jcm 14k?
DQ means Diamonique, CZ means Cubic Zirconia, JCM is the makers mark and 14k is the karat of your gold. So your necklace is real 14k gold, but the stones in it are Cubic Zirconias made to look like diamonds. JCM is the signature of the company that made your necklace.
