Many swimming pools use chlorine in large proportions for cleaning. Some pools are not so heavily chlorinated. The Chlorine chemical can react with the metal on your rings, earrings or necklace and lead to corrosion and lose your precious gemstones.
Most jewelry is combined with other metals to create an alloy. Jewelers use these other metals in order to harden jewelry to make it more durable for everyday use. The most common alloy metals that are used with gold jewelry are Nickel, Copper, Silver, Zinc, Palladium, and/or Cobalt.
The Chlorine react with alloys to form new substances and left many tiny small holes in your jewelry. You may not see some of the effects immediately, but if you put your jewelry under a microscope you would be able to see pitting beginning.

Because of these tiny small holes, there is no strength like hallow in prongs of the jewelry and these prongs hold gemstones that become weak and snap off. And the gemstones in your jewelry may fall off over time.

We also should have to be aware some gold jewelry (less than 18K) that have many alloy proportions. The more alloy proportions in your jewelry, the more reaction can be fasten. Moreover we also take care of White Gold Jewelry than Yellow Gold Jewelry and Pink (Rose) Gold Jewelry.

In order to harden White Gold Jewelry, we use alloy that include Zinc, Nickel, Palladium, Cobalt and Copper.
For Yellow Gold Jewelry and Pink Gold Jewelry, we use Copper and Silver as alloy.

According to the Reactivity Series of Metal List, react to Chlorine quickly. So White Gold Jewelry is very vulnerable to Chlorine than Yellow Gold and Pink (Rose) Gold Jewelry.
Besides some common gemstones that are damaged in chlorine swimming pools. Pearls, Amber, Coral and Ivory are organic that once living, or produced by a living organism (plant or animal). These gemstones vary in porosity so some are more vulnerable than others are to chemical damage. The chemicals can dull or even pit the surface of these gemstones.
Diamond, ruby, sapphire gemstones are completely resistant to chlorine and the least reactive metals would be Platinum too. So we should remove our jewelry before swimming in a chlorine swimming pool or hot tub. If we have, please rinse our jewelry well in fresh water.
By taking this chance of sharing the knowledge we've learned, we would like to thank to each and everyone of our customers who continuously supporting us from the beginning. Thank you so much! We feel very grateful to be able to continue our passion. We will work harder to become a jewelry shop which could bring you happiness.
