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.

If you like the color green then you should know just how they create green diamonds. We are all aware that diamonds can be created either by nature or in a lab. These are other wise know as lab grown diamonds. But are these colored stones really worth the asking price.

We have seen some really high prices on diamonds and it is the fact that the lay man does not know how it is made.

It goes without saying that a diamond is a girl’s best friend. But she’s guaranteed to love it if it’s original. What’s the best way to make it unique? Give it a little color.

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.

The Diamond is known as an allotrope of carbon and is the hardest natural mineral in the world. Where do diamonds come from? – Diamonds are formed through carbon which is derived from the melting of pre-existing rocks in the Earth’s upper mantle. Due to an massive presence of carbon atoms in the mantle and the extreme temperature changes and adjustments in the upper mantle forces the carbon atoms to go deeper where they melts and forms new rock; as the temperature falls and other conditions, namely pressure remain the same then the carbon atoms in the melting crystal rock bond together to build diamonds. These diamonds are then pushed to the surface through volcanic activity and when they cool mines are formed. These mines are called Kimberlite Pipes and the diamonds take thousands of year s to get to the surface when this phenomenon occurs. The best type of Diamonds are those that are cut finely to fit in any jewelry piece.

The most astounding fact about a diamond is that it is truly indestructible except when smashed against another diamond. Only a diamond can scrape another diamond. There are four major C’s in a Diamond Value:

• Carat And Color
• Clarity And Cut.

Diamonds are produced the most in the following countries:

• Africa
• Russia
• Australia
• India
• South America
