Definition of diamond
The word "Diamond" comes from the greek word "Adamas", which means indestructible. It is the only gem known to man that is made of a single element, Carbon. Diamond is completely made of Carbon atoms (Chemical Composition - 'C') crystallised in a cubic (isometric) arrangement.
Diamonds form between 120-200 kms or 75-120 miles below the earth's
How to buy diamonds:
There are 4 ‘C’s to be considered while buying diamonds, Clarity, Cut, Color & Carat.
Clarity of diamond:
The formation of a diamond is not a gentle process. Most diamonds are born in extreme circumstances from primeval carbon deep in the earth’s mantle at about 500,000 to 2 million feet below the surface. They are then shot up to the surface at supersonic speeds by eruptions inside the earth. These volcanoes are very small. The extreme heat and pressure that diamonds undergo during their ascent can cause unique “birthmarks” that affect their clarity.

Cut of diamond:
The way a diamond is cut will have the biggest effect on how the stone catches and interacts with light. It is the ultimate expression of a craftsman's skill in transforming a rough diamond into a breathtaking gem. If the diamond is too shallow and not cut right, some of the light will be lost out of the bottom. One that is cut too deeply will lose light out the side of its base. An Ideal Cut diamond will reflect most of the light through their table or top surface.

Color of diamond:
Diamond collections include the following natural color hues: yellow, pink, red, orange, green, blue, and purple.
Carat of diamond:
A carat (ct.) is the unit of measurement specifically used to describe the weight of a diamond (or other gemstones). Its name comes from the carob seed – a small seed with a typically uniform weight that early gem traders used as counterweights for balancing their scales, according to the GIA. A single carat is equivalent to 0.2 grams, or 200 milligrams, and is divided into 100 points.
