Refers to the symmetry and proportions achieved when cutting and polishing a diamond, and the finish and polish of the stone and is determined by the shape and quality of manufacturing.
Since the quality of the cut is directly responsible for the stone's beauty, the precision with which the facets are arranged is of prime importance. They determine the amount of light reflected to the eye, called brilliance. The better the diamond’s cut, the more brilliant it appears, hence imparting greater value to the diamond.
Formerly, the most appropriate way of cutting a particular piece of rough was entirely dependent on human judgement. But now there are computerized systems that take accurate measurements of a rough diamond and based on mathematical calculations help determine the most appropriate cut.
The most common shape is the round also called the brilliant. It has 58 facets and because it is symmetrical, it reflects nearly all light that enters it. The round brilliant cut has been mathematically researched to produce the maximum brilliance from the diamond’s natural properties.
However there are an array of other shapes as well. Some of these include marquise, pear shaped, heart shaped, the rectangular emerald cut, the square princess cut, and the cushion cut. |
