NATIONAL GEOGRAPHIC Birthstone Dig Kit - STEM Science Kit, Birthstones

NATIONAL GEOGRAPHIC four-stage silicon carbide grit for rock tumbling systems is the ideal way to give rough rocks a smooth, polished look. The first rock polishing stage smooths rough edges and provides initial shaping. The second stage smooths the rock surfaces even more. The third stage provides a strong pre-polish, followed by the fourth stage which completes the grit polishing process.
