The value of a piece of diamond is depending on its Color, Clarity, Cut and Carat. These are the 4C of the diamond. Color Diamond is graded into different colors from D colorless to Z light yellow. Most common color ranges are color D, E, F (colorless), G, H, I, J (Near colorless) and K, L, M (Faint). Color affects the value of the diamond. Clarity They are the minute traces of other materials inside the diamond. Size and position of these materials determine the clarity and hence the value. 10 times magnifying glass is usually the instrument used for clarity grading. Clarity ranges are FL (Flawless), IF (Internally Flawless), VVS (Very Very Small inclusions), VS (Very Small inclusions), SI (Small Inclusions), and I (Included eye visible inclusions). Cut If a diamond is cut with right proportions it will display the greatest amount of brilliance. Cut too shallow, light escapes through the pavilion. Cut too deep, light escape through the opposite side of the pavilion. Well cut, light is reflected from one facet to another and dispersed through the top of the diamond. Most commonly found diamond shapes in market are circle, Oval, Marquise, Heart, Pear and Square. Carat Weight of diamond is measured in carats. A carat is divided into 100 points. Larger diamonds are rare and prices are relatively higher. However, other than size, color, clarity and cut determine the price as well.  Storage Though diamond is hard, never put 2 or more diamond jewelleries together.
