Do Pearls Tarnish? The Honest Truth

Care & Trust · July 11, 2026 · 4 min read

Strictly speaking, pearls don't tarnish the way silver does. Tarnish is a chemical reaction on metal surfaces; pearls are organic gems. But pearls can lose their lustre and become dull or yellow over time — which people often describe as tarnishing. Understanding the difference helps you care for them properly.

Pearls vs metal tarnish

  • Metal tarnish — a dull film from oxidation (silver is the classic example).
  • Pearl dulling — loss of lustre from chemicals, dryness, or aging.
  • The fixes are different — metal tarnish polishes off; pearl dulling needs gentle care.

What actually dulls pearls

  • Perfume, hairspray, and cosmetics.
  • Heat, strong light, and dry air.
  • Sweat and skin acids over time.
  • Harsh cleaners and ultrasonic machines.

How to prevent dulling

  • Put pearls on last, take them off first.
  • Wipe with a soft dry cloth after wearing.
  • Store properly with a little humidity.
  • Wear them regularly — skin oils keep pearls hydrated.
