Swimming pools expose jewelry to chemicals, changing finger size, and a significant risk of loss.

Chlorine and jewelry metals

Chlorinated water can interact with alloy metals used in some gold jewelry. Repeated or prolonged exposure may contribute to discoloration or weakening, depending on the alloy and concentration.

Why rings become easier to lose

Cold water can temporarily reduce finger size. A ring that fits securely on dry land may loosen in the pool and slip off unnoticed.

Settings and finishes

Residue can collect around prongs and beneath stones. Plated, oxidized, or specialty finishes may also respond differently than untreated solid metal.

Best general practice

Many jewelers recommend removing fine jewelry before entering a chlorinated pool. Store it securely before arriving rather than placing it in a towel, pocket, or poolside bag where it can be misplaced.

The exact level of risk depends on the metal alloy, finish, stone, setting, and condition of the piece.
