How to clean jewelry with gemstones

Each stone has its own hardness and sensitivity. Before cleaning, identify the stone: not all of them tolerate the same method.

Tough stones #

Diamond, sapphire and ruby handle lukewarm soapy water and a soft brush. Even so, avoid knocks and sudden temperature changes.

Delicate stones #

Pearls, opal, turquoise, coral, amber, lapis lazuli and jet are soft or porous: clean them only with a damp cloth. Emerald often has fractures treated with oil or resin, so do not use ultrasonic, steam or solvents.

Glued stones #

If the stones are glued (as in much costume jewelry), do not soak them: water can loosen the glue.

Safe steps #

1. Wet a soft cloth with lukewarm water and a drop of mild soap.
2. Wipe the piece carefully, using a soft brush in the crevices.
3. Rinse with another damp cloth.
4. Dry well.
