Jewelry Care & Cleaning

Keep your jewelry looking beautiful for years to come by following these simple steps:

  • Remember; “Last on, First off”. Make sure your jewelry is the last thing you put on, after beauty products and the first thing you take off. 
  • Never wear your jewelry while swimming in a chlorine pool and avoid wearing it while bathing.
  • Use warm water to clean it, then pat dry. We do not recommend using jewelry cleaner.
  • To avoid black markings on your skin or jewelry, use our Milestones “Blitz” polishing cloth regularly. Available for as low as $1.99.
  • Do not store your Jewelry in the bathroom. Bathrooms tend to have excessive moisture which can tarnish your jewelry. 
  • Store your jewelry separately, in a plastic bag (one piece per bag) or anti-tarnish bag.
