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.

Is that colored diamond really worth it? We wanted to know how do they create green diamonds, but the reality is the colored diamond is prime yet has many impurities and honestly might just not be worth the cost that retailers are peddling them for.

When it comes right down to it, the sparkle in that diamond would never hint to its underground birth. As the jewel is formed, different amounts of heat and pressured are experienced and this determines the diamonds appearance. When the stone absorbs chemicals, it changes hues. Nitrogen gives a yellowish-brown tint; carbon produces a blue or pink tint; and nuclear rays generate something even more spectacular.

As a diamond is forming, it comes in contact with many elements. In rare instances, nuclear rays mix with the jewel and the result is an green colored stone. The certification of this diamond is based on its hue and intensity, which is determined by either a gemologist or the jeweler.

If the color of the stone isn’t to the buyer’s liking, or if an original green diamond is too rare to be found, a gemologist can perform various processes of color treatment to achieve the desired effect. This includes applying electron beams in linear accelerators and heavy nuclear rays to the stone. The result is a natural looking stone with a green tint.

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.
