Diamond is the most famous precious stone thus many various kinds of diamonds are worn all over the world. That precious stone comes in different colors like yellow with brown shimmer and famous white with blue and pink shimmer. Such kinds of diamonds are more expensive than simply yellow or simply brown stones because of the labor-intensive and time-taking process of making that diamonds ideally shaped and removing that grey and brown shimmer in blue and pink stones accordingly. But the most expensive diamond is those completely transparent. Here, the web-store, a trading mark of KTD Group s.r.o. suggests you to have a small guidance through the diamonds life.

Having a quick look at the history we may find that the word “diamond” is formed from two ancient words that mean “unalterable” and “overpower”. That word has Greek roots in spite of the fact that the first diamond was mined in India where the stone is already known more than for six thousand years. During all the human history diamonds were used as accessories that were decorating the human body. The most important gem diamond’s characteristic is the ability to separate light into spectral colors. There are also four main diamond’s characteristics that were developed by scientists in the twentieth century; they are clarity, color, cut and carat.

Looking at the physical parameters, the diamond’s ultraviolet wavelength that causes a wide band gap of the stone is more than two hundred nanometers. For those who are not physicists we explain that all mentioned parameters suggest the diamond to be a clear colorless crystal transmitting the light. But what is about the colors? The various coloring of the diamond is caused by impurities and defects in the stone’s lattice. By the way, its lattice makes the diamond one of the strongest materials in the world.

Only hydrogen, boron and nitrogen atoms may be placed into diamond. Notice that the major impurities of gem diamonds are caused by nitrogen. This is exactly the atom that is responsible for the brown and yellow coloring of the stone. Green coloring is caused by the irradiation presence. Plastic deformation also known as diamond’s crystal physical deformation is responsible for pink and red coloring.

It’s too difficult to find absolutely transparent and colorless diamond because of its rarity; usually diamonds come to us in red, purple, orange, violet, pink, translucent white, black, green and finely blue is the most common coloring. Black diamond has its coloring owing to numerous dark inclusions. All this colorings are caused by a carbon flaw, the phenomenon of carbons’ atoms replacing by various impurities in the diamond’s crystal lattice.
