Jewelry in Pools, Hot Tubs and the Sea: What to Take Off and Why

Water itself won't hurt fine jewelry. What's in the water — and what the water does to your fingers — is another matter.

Written by the Mapple Gems workshop, Surat · Updated 25 September 2026

Short answer

Take fine jewelry off before swimming pools and hot tubs. Chlorine and bromine can attack gold alloys, especially over repeated exposure, and hot tubs combine chemicals with heat. In the sea, the bigger risk is loss: cold water shrinks fingers so rings slip off unnoticed. Moissanite and diamond themselves are unaffected — it's the metal and the fit that suffer.

People are often surprised that the advice isn't about the stones. Moissanite (Mohs 9.25) and diamond (Mohs 10) don't mind water, chlorine or salt. Gold, and the tiny prongs holding your stones, are a different story.

What each kind of water does

Water	Main risk	Advice
Chlorinated pool	Chemical attack on gold alloys	Take jewelry off
Hot tub / spa	Chemicals plus heat	Take jewelry off
Sea	Loss from shrunken fingers; sand abrasion	Leave rings in a safe place
Shower	Soap film dulls stones	Best removed; rinse if not

Chlorine's damage to gold is slow and invisible at first. Karat gold is an alloy — gold mixed with other metals — and chlorine can attack those other metals, particularly at points already under stress, like a prong bent tight around a stone or a ring that's been resized. Over time that can lead to tiny cracks. You won't see it after one swim; you might see it after a summer of daily pool visits, as a prong that snaps or a stone that works loose. White gold's rhodium finish can also dull faster. That's why the simplest advice — take it off — is also the one that saves the most repairs.

Holiday habits that save jewelry

Pack a small zipped pouch and put jewelry in it before the pool, not after. Don't leave rings on a sun lounger or towel — that's where they're lost. After any swim with jewelry on, rinse it in fresh water and dry it. For travel advice, see cleaning and moissanite and chemicals.
