The tang is considered the most commonly used tool in the diamond polishing process. The modern day polishing process largely uses the same traditional tools that have been used in the industry for decades.
The tang, a traditional and old tool, is the polishing base which is made up of two main parts; the arm, which features fixed but adjustable legs on one end, and the clasp that holds the diamond during the polishing process on the other. The tang’s clasp contains a “dop,” which grasps the diamond during the polishing process.
The dop can be adjusted to any angle using screws, arms and a copper rod.
