Zirconia and diamond are very similar in appearance and properties, and as such are very difficult to distinguish. They are distinguished by the naked eye is virtually impossible with the jewelers only able to keep them separate. The main differences are in weight, hardness, and of course price.
History
Diamonds have existed in nature for hundreds of years, and the first laboratory diamond was introduced in 2004. On the other hand, theCZ crystals were first discovered in Germany in 1937, but produced artificially in the Soviet Union in 1973 and marketed by.
Weight
CZ is about 1.7 times heavier than diamonds of equal size.
Hardness
Diamonds are known for their hardness. You are one of the hardest materials known to man. Measure 10 in the Mohs scale of hardness, while the policies CZ 8.5.
Price
The differences are not perhaps soparticularly significant when these two materials are used in jewelry. However, the cost of the most important factor that will kilometers were removed. The difference is striking, perhaps as a figure of $ 10,000 to $ 1 can prove this.
Refraction
CZ refractive index 2.17, while a diamond is 1.417. Then breaks Zirconia shed more light, the surface brighter and brighter.
Heat and fire
CZ are resistant to heat and use them as insulation.Exposed to fire, light up orange. The heat is easy with diamonds, and that turn orange and blue under enemy fire.
Look
Zirconia and diamonds seem to be indistinguishable, which is visible to the naked eye, but with a powerful microscope to observe that these have a greater luster, and more color. They also have some shortcomings, because the stones are natural and artificial against CZ.
This makes it very difficult to buy real diamondsespecially on-line or non-certified sources. Here are several steps to recognize what is and what a diamond is a stone CZ:
1. Buy or borrow a magnifying glass.
2. If you wear. Diamonds are very difficult and as such are virtually resistant to wear.
3. Try hardness. The diamonds are very difficult and can be broken only with specific heat, while the CZ is brittle and break easily.
4. Weigh the CZ, in contrast to a similar piece of diamond. Zirconia isheavier.
5. Check the color. Most diamonds have a hint of color, while the CZ is completely transparent when placed in a different color.
6. CZ stones are flawless, but not diamonds.
