Zircon is made of zirconium silicate, whereas cubic zirconia is made of zirconium oxide. Both of the gemstones are hard to differentiate from each other and are confused as being the same. … Zircon is a natural gemstone. Natural zircon is rare and more expensive than cubic zirconia.
Are zircons expensive?
Zircon can cost anywhere around $50 to $400 per carat, depending on the quality factors of the stone. You’ll need to evaluate the stone and ensure that it is worth the asking price. It is best to compare the zircon prices from different vendors before you buy, to ensure you are getting a good deal.
How can you tell if a zircon is real?
The most obvious way to distinguish a zircon presented as a substitute diamond from an actual diamond is by the former’s birefringence. Zircon’s high birefringence makes this 4.57-ct round brilliant-cut stone appear fuzzy.
Is cubic zirconia the same as zirconium?
Cubic zirconia and cubic zirconium are not the same thing. The suffixes -ia and -ium make a big difference in the meaning of the terms. CZ is the abbreviated name given to the world’s most popular diamond simulant, cubic zirconia. Cubic zirconia is manmade crystalline zirconium dioxide, ZnO2.
Is zircon a fake diamond?
Cubic zirconia is a real, man-made gemstone. It’s a crystalline form of zirconium dioxide that’s hard and colorless. But cubic zirconia should not be considered a diamond under any scenario by both experts and non-experts.
What is Swarovski zirconia?
Swarovski Zirconia is not a synthetic diamond, but it is commonly known as a diamond imitation. … Synthetic diamonds are an exact replication of natural diamonds, except that they are created in a laboratory instead of being mined.
Is zircon rarer than diamond?
Colorless zircons may produce highly convincing diamond imitations and even outshine poor diamonds when cut appropriately. Interestingly, zircon is actually rarer than diamond, despite its lengthy history as a diamond replacement. However, mimicry can only get you so far.
Is cubic zirconia real or fake?
Is a Cubic Zirconia Real? A cubic zirconia is a real cubic zirconia, but it is not a real diamond. There are a few types of stones that are used as diamond simulants, but cubic zirconia is by far the most common and the most realistic.
Is cubic zirconia plastic?
This crystalline material (or CZ) is synthetic, which means it is created in a laboratory. Due to increased demand, commercial production of CZ began in the 1970s. Since cubic zirconia mimics a diamond but is not the same material, it is referred to as faux, fake, imitation, and stimulant.
Can zircon go in water?
Water: Some water is OK and can cause no problems in your jewelry after years of exposure.
How do you get zirconia from zircon?
Zircon can be processed to create zirconia by melting the sand at very high temperatures, typically above 2,600oC, in an electric arc furnace to form molten zirconia, also known as zirconium oxide (ZrO2).
What is zircon worth?
Prices for blue zircons average around $75 per carat for 5 to 6 carat gems. The better colors with fancy shapes can wholesale from $125 to $150 per carat. Top gem blues can reach $200 per carat. Stones over 10 carats range from $150 to $175 per carat.
Can cubic zirconia pass a diamond tester?
Can CZ pass a diamond tester? No. Cubic Zirconia (or CZ) does not have high enough electrical conductivity to pass. So, when you test a CZ with a diamond tester, it will not show as diamond.
Are cubic zirconia lab diamonds?
What is the difference between lab diamonds and cubic zirconia? Quite simply, a laboratory-grown diamond is a diamond: carbon atoms arranged in a diamond cubic crystal structure. The only difference between mined diamonds and lab grown diamonds is the origin of the diamond. … A cubic zirconia is not a diamond.
Why is cubic zirconia cheap?
Cubic zirconia is very inexpensive, since it’s synthetic and mass-produced. A cut and polished one carat cubic zirconia stone will cost $20 and a similar two carat stone will cost about $30. This is far cheaper than diamonds, which start at $1800 for one carat and increase considerably as size goes up.
