Diamonds are polished into a variety of shapes. The choice of shape is mostly one of taste, best use of the pre-polished rough diamond, and, at times, color. Most call a diamond's shape "cut." However, since January 2006, the term "cut" has referred to the proportions of the diamond, its Cut Grade, and the term "shape" has since been the term for the form or contour of diamonds.
According to Ehud, education, like marketing, is an essential component in creating a critical mass of believers in diamonds for wealth preservation.
