Diamond – unique mineral, along with graphite represents one of carbon forms. Diamond is known for the reference hardness, high heat conductivity, transparency for any lengths of waves and also chemical stability. All these properties explain its broad application in the technical purposes. The jewelry product of processing of diamond - diamond is more interesting to ordinary inhabitants.
Smell as physical properties
The smell belongs to the list of physical properties of substance along with color, taste, density, hardness, conductivity, solubility. It is defined by ability of substance at evaporation on air to cause irritation of organs of smell in living organisms. However this criterion is very individual and depends on perception of the specific person. Even the same smell is perceived by people differently. It will be pleasant to someone, and someone will call it disgusting. Besides, in view of features of an organism, a part of people does not perceive smells at all.
In the world there are about three million organic compounds, and only the fifth part of them possesses a smell. The majority of odorous connections have plant or animal origin. However, if we do not feel a smell, it not always means its absence at substance. For olfactory receptors of the person there is a concept of a zapakhovy threshold when concentration of molecules of substance in cubic centimeter of air exceeds a certain size. By the way, for a dog this indicator is less than thousands of times in hundreds and it is enough that the animal guessed any given substance. Not without reason dogs are so irreplaceable in search works.
Smell as property of diamond
Now we will pass to diamond. On the Internet it is possible to read hundreds of councils for unprepared people how to distinguish the real diamond. Having Let's say found accidentally unusual stone and having suspected of it diamond, somebody wants to know available ways to check the guesses in house conditions. Of course, presence at diamond of a smell could be great help in diagnostics of authenticity of these stones. Why to use difficult devices, the spectral analysis when it is only enough to smell, and everything will become clear? Alas, it is only dreams and harmless irony. Because diamond has no smell. If to speak language of the physical phenomena, from the surface of this mineral there is no evaporation of the volatiles which are responsible for a smell. And it is possible to achieve transition of diamond from a firm state in gaseous only in vitro. For example, temperature of melting of diamond is 4000 wasps, burning on air - about 1000 wasps.
To look for natural diamond or diamond on a smell – absolutely useless occupation. And other national ways are extremely doubtful and unreliable. Diagnostics of authenticity of diamond is carried out only in vitro. And the diamond acquired without piece of jewelry has to have a certificate issued by the gemological center.
