Grinding
The grinding shape of a diamond is the shape in which the rough diamond is sharpened before the diamond is processed in a jewel. There are many different forms in which a diamond is sharpened. The most famous grinding shapes are, for example, the Brilliant, Princess, Emerald and Hearts & Arrows.
The value of a diamond is determined on the basis of four factors, the 4Cs:
- Cut (grinding shape)
- Color (color)
- Clarity (brightness)
- Caratweight (carat weight)
Of these 4Cs, the grinding shape is the only factor that people can influence. It requires craftsmanship and even mathematics to transform a rough diamond into a sharpened diamond. For example, the diamond cutter has to deal with perfect proportions, finish and symmetry. This is important because these factors determine the sparkle and the "fire" (the refraction and reflection of the light of the diamond).
