How to distinguish fianit from a diamond

The cherished dream of every woman is to have an ornament with a diamond. In recent years, a lot of products with artificial stones (zircons , cubic zirconia) of the highest quality appeared on sale, and it is completely incomprehensible at first glance - how to distinguish fianit from diamond? To do this, you need to know a little about the origin of phianites and their characteristics.

What is fianit?

Fianit is a synthetic crystal artificially created in the laboratory of the LPI of the USSR, which is zirconium dioxide in its structure . This material was not originally intended for jewelry, it was necessary to create a laser, as it was one of its constituent elements. This artificial crystal had prescribed optical properties and was free from defects that are inherent in natural stones. Its first purpose is a high-quality lens for optical instruments, quantum generators. Fianit withstands an aggressive environment, high temperatures (more than 2,500 degrees), which allows it to be used in the chemical industry. But thanks to its high physical performance, very quickly the purest crystal of cubic zirconia was used in jewelry as an artificial diamond. How to distinguish fianit from a diamond? There are special gemological tests to determine which stone is in front of you. By the way, fianit can imitate sapphires, rubies and other stones. A little observation and knowledge about the composition of crystals - and you can show the master class "How to distinguish fianit from a diamond".

Choose a diamond

The first and most important quality of a diamond is hardness. On the scale of hardness of minerals, the diamond occupies the highest step, that is, it can not be scratched, just with the same diamond. Fianit is much softer. You can try to hold a diamond on the glass - and he will leave a scratch. Fianit is not capable of scratching hard minerals, even ordinary glass.

The next moment is inclusion. All natural stones have in one way or another inclusions - cracks, discoloration, etc. It should be known that diamonds of purest water (without inclusions) in nature are extremely rare and they are fabulously expensive.

Try to look at the light through a cut diamond - a diamond. If this is a real stone, you will see only a luminous point in the center due to the refraction of the rays from the rear faces. But through the artificial crystal light passes, and you can see through the large artificial stone in the ring the finger on which this ring is worn.

But the most correct test is performed by a gemologist on thermal conductivity. This requires a special device. It will show the level of thermal conductivity from the surface of the stone. Natural diamond has a very high thermal conductivity. It is impossible to create an artificial crystal with the same high index.

And the easiest way how to distinguish a fianite from a diamond is at a price. How much is the fianite and the same size diamond? Even a small diamond with a low index is a valuable natural stone. Therefore, jewelry with diamonds, even with a diamond crumb, will be much more expensive than products with a large and clean, but artificial cubic zirconia.
