Going swimming in a pool with chlorinated water can be detrimental to your gold rings, either white, yellow, or pink.
In a single season, the chlorine can dissolve enough gold
to loosen or destroy the tiny prongs holding your gems.

Chlorine can be very harmful to karat gold of any kind.
But jewelry made of white gold, now so popular, is especially susceptible to damage from chlorine. Even minuscule amounts
of diluted chlorine will erode the nickel alloy in white gold and possibly lead to damaged prongs and settings.

It also pays to be careful of chlorinated chemicals used daily in your home. These include bleach, detergent, soaps, and cleansers. Evaporation can increase the chlorine level in these products and leave concentrated deposits on your gold rings with very unfortunate results.

You should actually keep all chemicals away from your jewelry.

This includes cleansers that you would use for your sinks, showers, ovens, counter tops, and floors. Keep your jewelry away from laundry bleach. Don't wear your jewelry in the swimming pool or hot tub and don't get hand sanitizers on your jewelry.
