How to clean and care for gemstone jewelry?

The safest, most effective way to clean gemstone jewelry is soaking the pieces in lukewarm water mixed with a few drops of mild, pH-neutral dish soap and gently scrubbing with a soft baby toothbrush. Different gemstones possess distinct mineral hardness levels, porosity, and heat sensitivity, meaning a single cleaning method cannot be universally applied to every stone.

Gemstone Sensitivity & Cleaning Compatibility

Gemstones react differently to heat, moisture, ultrasonic vibrations, and chemicals depending on their chemical composition and structural integrity.

Gemstone Category Examples Mohs Hardness Safe Cleaning Method Avoid Completely
Hard Non-Porous Diamond, Ruby, Sapphire 9.0 – 10.0 Mild soap bath, warm water, soft brush, steam Thermal shock (extreme heat jumps)
Medium Hardness Aquamarine, Topaz, Amethyst, Garnet 7.0 – 8.0 Lukewarm soapy water, soft microfiber cloth Ultrasonic cleaners (if fractured/filled)
Soft & Fractured Emerald, Tanzanite, Peridot 6.5 – 7.5 Room-temperature water, gentle wiping only Ultrasonic, steam, hot water, harsh chemicals
Porous & Organic Pearl, Opal, Turquoise, Coral, Amber 2.5 – 6.5 Damp soft cloth, immediate air-dry Submersion in water, soap, ultrasonic, alcohol
