To ensure that your jewelry stays bright, keep it in an airtight container or a sealed bag like Ziploc. After each use quickly give it a clean with a dry cloth before placing into airtight bag or container. We recommend putting your jewelry on last when getting ready, as direct exposure to hair-styling products & perfume will often also damage the metal & gemstones. Do NOT use jewelry when swimming in chlorinated, thermal or salt water OR when showering. Also avoid wearing silver while exercising as this will cause sweat & other toxins, which can contribute to tarnish.
