This paste is often used in various industries, including manufacturing and jewelry, to achieve a smooth and shiny finish on metals, glass, and ceramics. The paste is typically applied to a polishing pad or cloth and can be used with machines or by hand. Different grades of diamond paste are available, allowing users to choose the appropriate coarseness for their specific polishing needs. This versatility makes it a valuable tool for precision work.
