Facet

^[1]

The method of cutting its surface into a series of flat reflecting surfaces to achieve the best effect of showing the beauty of transparent gemstones is faceting. The specific steps are as follows:

1. The gem is glued to a fixed object called a chuck, supported on a horizontal runner, and the runner controls the grinding powder for polishing the crystal surface;

2. Facet along certain angles in some special geometric positions.

During the cutting process, a large amount of gemstone material is ground awayoften as much as half or more of the gemstonebut the value of the finished gemstone is greatly increased. Faceting is a relatively complicated process. You must pay attention to the crystal orientation of the gemstone to show its optimal color (or minimize the noise in multicolor gemstones), to maintain the integrity of the raw materials to the maximum extent, and to display the best gloss. ^[2]
