Copper polishing lap for lapidary gemstones is preferred based on several reasons relating to uses. Some of the common uses of this lap include:
- For pre-polishing hard stones: Copper polishing lap can be used for preliminary smoothing, involving an excellent coarse polishing compound and buffing. The abrasive process of removing a small amount of the surface from gemstones is called buffing. For pre-polishing, copper polishing lap for lapidary gemstones will only remove minor scratches left on the surfaces after sanding and smoothing and not produce a bright polish.
- For the final polishing of hard stones: Copper polishing laps can be used for the final mirror finish by polishing gemstones. For polishing, harder compounds (such as rouge) are used. There is no cutting action with a compound like rouge– it only brushes the stones, moving the surface layer around to smooth the fine scratches that buffing fails to deal with.
