How to distinguish cubic zirconias from diamonds at home
How to distinguish cubic zirconia from diamonds? Is it possible to do this at home? It excites many. Let's look at these issues in detail.
What is a fianit, and how does it differ from a diamond?
How to distinguish cubic zirconia from diamonds? Cubic zirconia is an artificial stone that is made in the laboratory. This is its main and defining difference from a diamond or zircon, although it looks like them very much. A diamond is a specially treated diamond, that is, natural crystalline carbon. Unlike a diamond or a diamond, cubic zirconia is less solid and dense in its physical and chemical properties and structure.
The first appearance of cubic zirconia
For the first time, cubic zirconia was “grown” in the sixties of the last century at the Physics Institute of the USSR Academy of Sciences. It was in honor of this Institute, he received his original name.
What is more expensive - cubic zirconia or diamond? Here the answer is obvious. Despite the fact that the cubic zirconia and the diamond are very similar in appearance, their value is incommensurable. Cubic zirconia is not considered a precious stone, and its value in the jewelry market is several times lower than the cost of diamonds.
The composition and properties of cubic zirconia
How to distinguish cubic zirconia from diamonds? In terms of its physico-chemical composition, cubic zirconia is cubic zirconia. Unlike its natural counterparts, it can have a huge amount of color shades. In the original initial state, the fianit is transparent absolutely and colorless. The color range of cubic zirconia depends on the content of various metals that are added to the raw materials during its production. For example, chromium gives the phianite a greenish tint, cerium - shades of red, yellow or orange spectrum, erbium gives pink, titanium - golden, and neodymium - purple hues.
Cubic zirconia, the price of which is much lower than the price of a diamond, is considered a unique material for the production of jewelry. The combination of elements in its production allows to imitate not only unique diamonds, such as black, but also natural stones such as rubies, aquamarines, alexandrites, moriones, sapphires, topazes and citrines.Fianits are unique in this respect and can repeat the color range of any of the existing gems.
The fianit, the price of which is quite acceptable, is also unique in that it surpasses even a diamond in its optical qualities, has, which is important for jewelry, purity, depth and a great game.
Fianite and diamond: the difference
Fianite and diamond, as noted above, have a completely different chemical composition and a different physical crystal structure. The most important and decisive difference between a diamond and cubic zirconia is their hardness, although such a traditional way, like the ability to scratch glass, will not work. Like the diamond, and the cubic zirconia scratch the glass surface equally. The only possibility of their difference is an attempt to draw a diamond face on the surface of the cubic zirconia. The diamond will definitely leave its mark on the surface of the cubic zirconia.
With the official cutting and processing of cubic zirconia, the difference between it and the diamond can be seen by external signs. Traditionally for diamonds, the standard number of faces is fifty-seven, and they are characterized by sharp edges.It is precisely fifty-seven facets that make it possible to achieve the maximum possible effect from the refraction of light inside a diamond. When cutting cubic zirconia, the number of faces and surfaces is usually less, and the faces and edges are more smooth and rounded. On these external signs, you can immediately determine whether it is a precious stone or artificial.
Perhaps the only absolutely correct way to determine the authenticity of a stone is to measure and compare its thermal conductivity. But this method requires the use of special equipment and is available only to specialists.
How to distinguish a cubic zirconia from a diamond at home?
How to distinguish cubic zirconias from diamonds at home? Another way to determine the authenticity of a stone that can be used independently at home, if cubic zirconia imitates a diamond in terms of the number and processing of faces, this is to apply a drop of fat or oil to the surface of the stone. On the surface of the gem the drop does not change and will remain in its original state. A drop of fat applied to the face of an artificial stone of fianite will split into small particles or form small individual droplets.
Also with the help of oil you can try to attach a stone to the glass. If an oiled stone sticks to glass, then it is a diamond, if not, then most likely it is a fianit.
If you put the cubic zirconia on the text in a newspaper or in a book, then it will be possible to read it, when using a diamond it cannot be done. In this regard, light can also be seen through the fianit, and only one light point can be seen through the diamond. In addition, the diamond in the sunlight shines stronger than cubic zirconia.
The stones have different thermal conductivity, so if you hold the diamond in the palm of your hand, it will remain cold and the fianit will quickly heat up.
If you breathe on the fianit, then he, unlike a diamond, sweats.
Since a diamond is a gem of natural origin, small inclusions, surface irregularities, small defects are quite often found in it, which practically cannot be found in an artificially created stone.
Also, the difference between these stones is their ability to withstand aggressive chemical exposure.
