All jewelry is made of either an implant grade surgical stainless steel, implant grade titanium, implant grade niobium or 14k solid gold. Jewelry made from these materials greatly reduce the risk of infection and allergic reactions, common problems found with use of jewelry made from inferior types of metal. Our ends are threadless and most of our hoops are clickers. Our 14k gold vendors are Buddha Jewelry, Junipurr Jewelry, and Body Gems. If we don't have an item in store from any of these vendors we are happy to special order it for you.
