*Too much Pool time is not a great idea for your Gold*
CHLORINE can weaken 14k and 18k gold over time, so just watch the amount of time your jewels are exposed or submerged, especially if you have a prong-set ring. Why? If the prongs get weak, your stones could fall out!
It's a smart idea to have your prongs checked by your jeweler to make sure they are still strong if you have worn your jewelry in the pool for a significant amount of time in the past.
