Can I put water on the 18K gold necklace when I take a shower?

pu1. Pure gold may not be discolored, but 18k may be discolored because there are other metals

OK

pu2. 18k is made up of 75% gold and 25% other metals. It's better to leave it out because there's a possibility of discoloration as you said. Depending on the ingredients in the soap, it can change color
