Understanding Diamonds
By David Chandler, Thu Dec 8th

A diamond is just pure carbon crystal. If you look at thechemistry of diamond, it is pure carbon. The arrangement of thecarbon atoms differently makes it a unique gem. A diamond isconsidered precious from the ancient times and is popular forits strength.

How a diamond is formed?

Diamonds are formed in the earth thousands of years ago underextreme heat and pressure. This extreme heat and pressure in theearth transforms this carbon into crystals and colorless.Although diamonds are formed in the earth, the volcanicactivities are thought to have brought them to the surface ofthe earth in the early days. Hence, these volcanic pipes arefound to have diamonds in them. When some of the minerals mixwith the carbon, the diamond takes some other color in it. Suchdiamonds that are colored are very rare and valued much than thenormal diamond, which is colorless.

How diamonds are valued?

Diamonds are valued by their Cut, Color, Clarity, and Caratweight. You should remember the four C's that are used to valuediamonds. Cut, Color, and Clarity are used to measure thequality of the diamond and the final C, which is Carat, is usedto measure the size of the diamond. Man creates cut in a diamondand the other C's are formed in nature.

Types of diamonds

When minerals are mixed in nature with the diamond, it gives thecharacteristic color for the diamond. Based on the type ofmineral that is mixed, we can classify the diamonds in to manytypes. The following are the colors that are found in thediamond.

Yellow: this color is formed when Nitrogen is combined withdiamond crystals. Blue: During the formation of the diamond ifelements of Boron are mixed then the diamond will be in bluecolor Green: Green color is caused due to a missed out atom inthe lattice of atoms. Brown: Any dislocation in the lattice ofatoms causes brown coloring in the diamonds. Pink: Dislocationsin the lattice missed out atoms, and some impurities that arenon-nitrogen causes pink color in diamonds.

Carat - The Measuring Unit

Carat is the unit that is used to measure diamonds. In theearlier days, diamonds were weighed by using the Carob treeseeds. A seed from this tree was considered as one carat.Now-a-days one carat is equivalent to 0.2 grams. Diamonds ofless than one carat are known as pointers. Suppose the weight ofdiamond is 0.18 grams, and then it is known as 18 pointers. Themore the carat the more is the price of the diamonds.
