Editor’s Note: Some years ago, the International Gem Society (IGS) conducted a survey of members’ polishing techniques. Here, you’ll find the results for peridot polishing. Whether you’re just starting to learn the art of gem cutting or just looking for a new way to tackle a problematic gem material, we hope these results provide some useful suggestions.

Peridot varieties can vary in hardness. If you’re polishing forsterite (7), consult the survey results for polishing gems with 7-8 hardness. For fayalite (6.5) and tephroite (6), take a look at the results for polishing gems with 4-6 hardness.
