When all is said and done, there are two factors that relate to a diamond's value. The value of a diamond depends upon both its internal and its external brilliance.

A diamond in a raw state is nothing much to look at. Only after cutting and polishing can the true beauty and splendor of a diamond be displayed and realized.

The second factor that relates to a diamond's value is the so-called "fire" of a stone. This is determined by the manner in which a diamond is cut. The height and angles of the cuts on the diamond are what really matters when it comes to the matter of diamond fire.
