One of the things that makes a diamond so expensive is the precise and strict controls of production necessary before it can be sold to any part of the world. Almost 49% of diamonds comes from southern and central Africa. Other countries where diamonds are abundant include Brazil, Canada, Australia and India. Diamonds vary in size, shape, color and weight. Each corresponding element contributes to the value of a diamond, thus, each is different its own subtle way. Here are some of the characteristics of a diamond that contributes to its value: 1. Color Diamonds that have the least color are the most expensive ones. Color may or may not been seen by the naked eye. The color of diamond is graded according to the following groupings. D: This is the grade that has the highest form. It is absolutely colorless and diamonds with this grade are classified as extremely rare. E: Colorless.

This is due to the fact that even if the stone is of perfect clarity and color, its brilliance may be dulled if not appropriately cut. Cut may be deep, shallow or of the perfect length. A cut that is too deep allows light to escape of the sides, thus making it look dull and dark. If it is too shallow, most of the light that is reflected is lost at the lower part or bottom, thus the diamond tend to loose its brilliance. 3.
