Achieving a perfect polish on small gems requires precision, preparation, and the right equipment. Start by ensuring the gems are clean, free from debris, and check for any surface imperfections. Use a high-speed polishing wheel or a rotary tool with controlled speed, and choose the appropriate polishing compound for the type of gem you’re working with, such as tin oxide for softer stones or diamond paste for harder ones. Begin the polishing process with a coarse abrasive to remove scratches, gradually progressing to finer abrasives like 1200-3000 grit, finishing with a very fine compound for a flawless shine.
