How are gems formed within the earth or how do we fashion gems into the shapes you see in jewelry? If it is how are they fashioned into shapes, we facet them by pressing them on a revolving flat surface that has abrasives on it. You make one facet or window-like spot, then turn it slightly and make another and another. If how they are fashioned within the earth, most theories are pretty close to "You put all the ingredients in a really hot place, put an incredible amount of pressure on it, and wait a real long time."
