The Ultimate Birthstone Cleaning Guide

Different birthstones need different care. A diamond can handle steam cleaning; an opal will crack if you look at it wrong. This guide breaks down the safest cleaning method for every stone in your collection.

Hard stones (Mohs 7+): amethyst, citrine, aquamarine, sapphire, ruby, diamond. These can handle warm soapy water, a soft brush, and even ultrasonic cleaners (with caution). Rinse well and dry with a lint-free cloth.

Medium stones (Mohs 6–7): garnet, peridot, tanzanite. Use warm soapy water and a soft brush only. Avoid ultrasonic cleaners, which can shake stones loose from their settings over time.

Soft or porous stones (Mohs <6): opal, pearl, turquoise, moonstone. Never soak these. Wipe gently with a damp cloth. Avoid chemicals, heat, and prolonged sunlight — opals can dehydrate and crack, pearls can yellow.

For metal care, a polishing cloth restores gold and silver in seconds. For stubborn tarnish on silver, a paste of baking soda and water works wonders. Store pieces separately to prevent harder stones from scratching softer ones.
