No. Pearls should never be exposed to water beyond brief, accidental contact. Chlorine, salt water, soap, and shampoo all damage the nacre, dulling the luster permanently. Always remove pearl jewelry before showering, swimming, washing dishes, or working out. Put pearls on after applying lotion, perfume, and hairspray.
Pearls are not stones — they are organic gems made of calcium carbonate crystals (nacre) bound together by a protein called conchiolin. Both materials are vulnerable to chemicals.
Chlorine breaks down the conchiolin binding the nacre layers together, causing them to flake or peel over time. Salt water dries out the nacre and dulls its surface. Soaps, shampoos, and detergents leave a film that builds up and obscures luster. Even hot water can soften the protein binder.
The general rule, often called the last on, first off rule, applies especially to pearls:
- Put pearl jewelry on after you've showered, applied skincare, done your makeup, and styled your hair.
- Take pearl jewelry off before you shower, swim, exercise, clean, or sleep.
To clean pearls after wear, simply wipe each pearl with a soft, slightly damp cloth — water alone, no soap — and let them air-dry on a soft cloth before storing. This removes skin oils and residue without harming the nacre.
A note for stainless steel + pearl pieces: even though the steel itself is waterproof, the pearl is not. Treat any piece containing pearls as pearl-first — keep it out of the water regardless of what the rest of the piece is made of.
