Smash those corners and points in the tumbler, wipe out saw marks on the lap, get those stones ready for some polish slurry. Use in tumblers, flat laps, sphere machines or wherever loose coarse and fine grinding grits are needed.

Available in various size and grit packagings from Diamond Pacific, Hi-Tech Diamond, Inland Lapidary, and Lapcraft. Follow up with various lapidary polishing options.
