Understanding Cuts in Gemstones

Common Cut Used on Gemstones :

Brilliant Cut :
A brilliant-cut gemstone has facets that are positioned and cut in such a way to radiate the best light from the gemstone. Gemstone cutters also make sure that the angles will enhance the brilliance of the gemstone. Such cuts are typically used for diamonds and transparent gemstones.

The most popular variation of all is the full-cut round brilliant, a popular engagement ring choice. It has fifty-seven or fifty-eight  facets. The single brilliant cut, on the other hand, has fewer facets of seventeen to eighteen. A variation of brilliant cut with triangular shape is called trillion while a square brilliant cut is also known as princess cuts.
