The Universal Safe Cleaning Method

If you are unsure of a gemstone's identity or treatments, use this safest method:

  1. Prepare warm, not hot, water with mild detergent-free dish soap.
  2. Soak jewelry for 5–10 minutes.
  3. Gently scrub behind the setting with a very soft brush.
  4. Rinse in a bowl of clean water, never over an open drain.
  5. Pat dry with a soft, lint-free cloth.

Ultrasonic & Steam Cleaners: Use with Extreme Caution

Ultrasonic cleaners can make diamonds sparkle, but vibrations and heat can damage many other gems or dissolve treatment oils.

Never use an ultrasonic cleaner on

  • Emeralds
  • Opals
  • Pearls
  • Tanzanite
  • Turquoise or lapis
  • Fractured or heavily included gems

Generally safe when unfractured

  • Diamonds
  • Sapphires and rubies
  • Solid gold and platinum

When in doubt, use the hand-washing method.

Storage & Daily Wear

Most gemstone damage occurs during wear and storage.

  • Mohs scale: A diamond can scratch sapphire, gold, and softer gems, so store pieces separately.
  • Chemicals: Put jewelry on last and take it off first around hairspray, perfume, cosmetics, and harsh chemicals.
  • Temperature shock: Sudden changes can fracture tanzanite, apatite, and opal.
  • Light sensitivity: Direct sun can fade amethyst, kunzite, and some topaz.
