Diamond Carat

Diamonds are sold in carats. Carat is a unit of weight and it comes from carob seed. It is the original unit of measure for traders of diamond all around the world. One carat is equal to 0.2 grams. However two diamonds of equal carat can have different prices based on other factors like clarity, cut or color. The price of the diamond increases as the carat weight increases, as the diamond gets larger and larger. Also if the carat weight increases you will have to pay the price on the basis of price per carat.

Diamonds can win hearts and have the power to uplift man from rags to riches. However like every other stone, there is a set of particular facts and figures that are quite interesting.

However the round brilliant is the most expensive cut of diamond.

Diamond Color

Color is quite an important characteristic that affects the look and quality of the diamond. Pure diamonds are perfectly colorless and transparent. However diamonds occur in a variety of colors like gray, blue, white, yellow, orange, green, pink, black, purple and brown.
