The most important factor in choosing a cleaning method is your stone's hardness on the Mohs scale. Here's how to clean each category safely:
Soft stones (Mohs 1โ5) โ Turquoise, lapis lazuli, selenite, howlite, opal. These stones are porous and easily damaged. Dry cloth only. Wipe gently with a soft, lint-free cloth after each wear. No water, no soap, no soaking. For porous stones, even brief contact with water can cause discoloration over time.
Medium stones (Mohs 5โ7) โ Amethyst, rose quartz, jade, obsidian, aventurine, carnelian. Mild soap and water. Use lukewarm water with a tiny drop of mild dish soap. Dip a soft cloth in the solution, wring it out thoroughly so it is just damp, and wipe each bead individually. Dry immediately with a clean soft cloth.
Hard stones (Mohs 7โ10) โ Clear quartz, citrine, garnet, tourmaline. Gentle rinse. You can briefly rinse these stones under cool running water, then dry thoroughly. Avoid hot water, which can cause thermal shock and crack the stone.
When in doubt, use a dry cloth. A gentle wipe is always safe for any stone.
