Carbonado is also known as Black Diamond. It is actually a poly crystalline substance that is available on the earth, especially in the mines. People have a great liking for this natural diamond and sometimes the demand grows high. Carbonado is used in making jewelry and crystals.

Therefore, special techniques have been innovated for making these polycrystalline substances from smaller crystalloids. This is an artificial method and is called Crystallography. This word originates from the Greek word crystallon meaning cold drop or frozen drop. The word graphein means something to write.

In the old days, the making of the crystals depended mainly on studying the geometry of the crystals. This was a tough method and therefore research was made into this field. Nowadays, crystallography depends mainly on studying the process of diffraction, which is done through X-Rays. There are three types of diffraction. They are neutron diffraction, electron diffraction and X-Ray diffraction.

The mantle-derived inclusions are lacking in the artificial carbonadoes. Moreover, the value of the carbon isotopes is also very low. The radioactive inclusions which makes the natural carbonados brighter and the natural luminescence is also lacking in the artificial carbonadoes. Therefore, people prefer the former. Yet due to lesser availability, artificial carbonadoes are also used.

Both diamond and coal are made up of carbon but the crystalline structure of these two isotopes of carbon varies giving more prestige to diamond rather than coal. Hence diamonds are transparent and coal is black.

While coal has a normal hexagonal crystalline structure in which carbon atoms are arranged in the shape of a hexagon, diamond atoms are compressed under heat and pressure to give an octagonal shape to it. Moreover, the carbon atoms in coal are arranged along a plane while in diamond the atoms arrange themselves in pyramidal form.

This heat compression may happen due to earth’s movement and subsequent pressure for millions of years. Nowadays, artificial diamonds can be prepared by external application of heat and pressure.

Both diamond and coal are found in mines. They remain mingled with each other and one needs to extract and separate the two substances. Afterwards, diamond is cut so that light entering into it suffers from total internal reflection and hence the brightness of the precious stone!

While the flat planes of coal can absorb all wavelengths of light, the diamond atom’s pyramidal plane reflects and refracts rays of unequal wave length. Thus diamond sparkles when light falls on it.

Diamonds come in a range of colors. We actually don’t know which diamond is really the best but we are sending out this poll to actually see what color type diamond is most favored. Diamond colors are created using different impurities the more impurities, the darker the color the diamond. Diamond can be the following colors: steel gray, white, blue, yellow, orange, red, green, pink to purple, brown, and black. Cast your vote in the poll and see which color ends up being the most popular. It can really affect your decision this Christmas was the most popular is the most loved and possibly the one that would be most complemented. As well as you might want to choose the least popular color diamond to get that unique look Slog the decision is yours – Go for the unique or the most popular. Incidentally colored diamonds really affect the price as well. A white diamond is considered most pure and hence will be the most expensive diamond.

As we look mainly on earrings we have included some options for you to look at when you make your Choice:
