I got curious and found a few net references that it's recommended to
remove gold (ex: rings) before going in swimming pools..
"
Remove gold jewelry before entering swimming pools. The chlorine in
the water will erode gold jewelry."
Gold is one of the least reactive metals. The classic reactant is aqua
regia. I doubt that a bit of chlorine in water would have much effect.
And anything that eats through gold will go wild when it hits the
copper.

"When Germany invaded Denmark in World War II, the Hungarian chemist
George de Hevesy dissolved the gold Nobel Prizes of Max von Laue and
James Franck into aqua regia to prevent the Nazis from stealing them.
He placed the resulting solution on a shelf in his laboratory at the
Niels Bohr Institute. It was subsequently ignored by the Nazis who
thought the jar—one of perhaps hundreds on the shelving—contained
common chemicals. After the war, de Hevesy returned to find the
solution undisturbed and precipitated the gold out of the acid. The
gold was returned to the Royal Swedish Academy of Sciences and the
Nobel Foundation presented new medals to Laue and Franck."
