Why zirconia (CZ) is becoming more popular it is desirable to replace the diamond? Gemologists can agree that CZ more than any other material, gemstone, in accordance with the characteristics of diamonds.
Most people, even trained gemologists, can not tell the difference between diamonds and CZ, the naked eye. In addition to the untrained eye, CZ looks identical to a diamond of good quality. But a closer examination, crystal pendant CZ slightly less bright (or bright) than diamond, and have more fire, lightning, or color.
CZ were originally developed for its Russian space programs. They were an alternative to diamonds that have been designed with the laser. CZ has a refractive index, dispersion and hardness of diamond is so incredibly close.
What are the main features that you can make the difference between diamonds and CZ? But remember, clearly distinguish the two gems, gemological equipment such as microscopes or magnifying glass should be used for testing and verification.
For a start look at the hardness factor: Did you know, the Czech Republic is between 8.5 to 9.0 Mohs hardness scale whereas diamond, sterling silver brooch one of the hardest materials known to man, with capacity of 10 is located at the top of the scale of hardness?
In addition, glass (or sand) is about 5 to 6 on the scale of hardness, therefore, dust and dirt without scratching CZ. In fact, scratch glass, like diamonds CZ regularly makes it more resistant to separation.
The main difference between diamonds and CZ is weight. CZ weight of heavy compared to the diamond, CZ will weigh approximately 1.75 times higher than a diamond of similar size. So basically, the weight of the CZ the same size as the one-carat diamond approximately 1.75 carats. Well ... Is not that interesting?
Modern production of CZ is almost flawless, while the diamond usually contains impurities and inclusions, or is there some kind of defect, whether it's feathers, including the crystal, or perhaps the remnants of the crystal faces of origin (eg, triangles).
As for color, in particular, the absence of color in rare diamonds are colorless, really, since most of them are a shade of yellow or brown to some extent. For comparison, the Czech Republic in most cases, be quite clear that a perfect "D" in color classification of diamonds.
Also under scrutiny with a magnifying glass, jewelry set accessories the line shapes differ from some of CZ diamonds. And the stones disperse light a little differently. Dispersion of only a scientific term for the destruction of light into its spectral colors. With the dispersion Power greater than diamond (0.060 vs. 0.044), more prismatic fire of CZ can be seen the untrained eye.
The variance based on the GEM index of refraction. In this case, the refractive index of just how to bend a beam of light, depending in which direction they go when it comes to the two materials of different density (such as between diamond and air, or between CZ and air). When the CZ has a refractive index 2.176, 2.417, compared with diamonds, diamonds, therefore, said to provide brighter than CZ.
Another difference between these two that the CZ gems thermal insulators-meaning, they reduce the rate of heat transfer, while diamonds are among the most efficient thermal conductors-meaning, they simply allow the heat passes through. Without testing gemstones heat, it can be difficult to separate them.
Remember that the 50/50 proposal to determine the gem by visual inspection, it is not a scientific method of authentication. That is why even certified gemologists gemology and proceed to use the equipment for testing and verification.
You are also pleased that the Czech Republic is not only durable and inexpensive, but, like diamonds, they come in all colors of the rainbow, making them even more desirable.
There have been many occasions to see if the jeweler can make the difference between diamond and cubic zirconia was only by examining the gems with the naked eye. Again and again he is not unique, jewelers can not tell the difference just gems. So now you can understand why the difference between diamond and cubic zirconia rests in the price, and the soul
