Brilliant Cut Diamonds
The art of diamond cutting began in the Middle Ages; the first known records of a diamond cutter's guild date all the way back to 1375! Over the years, the types of cuts used and the technology used to make them have evolved into a precise art. Today, laser cutting and computer-aided design help cutters maximize a diamond's beauty.
Some people believe that "cut” refers to the end shape of a stone (ie, oval,)
but in fact the cut of a diamond pertains to the symmetry, proportioning, and polishing of the stone. A good cut can greatly enhance a diamond's luminosity, whereas a poor cut can result in loss of quality of the stone. The cut of the diamond greatly affects the stone's grade.
