TL;DR: Swimming pools genuinely risk your ring more than most people realise — chlorine can damage certain metals and gemstone treatments, cold water causes fingers to shrink, and a ring can slip off unnoticed underwater. Open water and the sea carry a real loss risk too. Removing the ring for swimming is the safest habit regardless of setting or metal.
Why Swimming Is Riskier Than It Seems
Two separate risks combine here: chemical exposure from chlorine, and finger shrinkage in cold water making a ring genuinely looser than usual. A ring that fits perfectly on land can slip off in the pool without you noticing until you're already out and drying off.
Chlorine and Metal
Chlorine can react with certain metal alloys over repeated exposure, and can affect the surface of some gemstone treatments (fracture-filled emeralds in particular). Platinum and 18ct gold tolerate occasional chlorine exposure reasonably well, but repeated, regular exposure — daily swimming, for example — adds up over time.
The Real Loss Risk
Cold water causes blood vessels in the fingers to constrict, which shrinks fingers slightly and can make an otherwise well-fitted ring loose enough to come off during swimming strokes or when removing a wetsuit or gloves. This is genuinely one of the more common ways engagement rings get lost — not through damage, but through simply slipping off unnoticed in the water.
By Situation
Swimming pools — remove the ring; chlorine exposure and cold-water finger shrinkage both apply.
Open water and the sea — remove the ring; the loss risk here is higher still, since a ring lost in open water or the sea is essentially unrecoverable.
Hot tubs and spas — remove the ring; heat and chemical concentration are both higher than a standard pool.
A Simple Habit
Keeping a small, secure pouch or case in your swim bag specifically for the ring removes the temptation to just leave it on "for five minutes" — which is how most swimming-related ring losses actually happen.

Frequently Asked Questions
Can you wear an engagement ring in a swimming pool? It's not recommended — chlorine exposure and cold-water finger shrinkage both increase the risk of damage or the ring slipping off unnoticed.
Why do rings come off more easily in water? Cold water causes fingers to shrink slightly, which can make an otherwise well-fitted ring loose enough to slip off during swimming.
