Yes, we do guarantee our jewelry. Although it is rare, some pieces of jewelry can have faulty pins or threading due to mass production. In the event you feel your jewelry may be faulty, please return to the studio to allow our piercers to assist you further. We offer free jewelry installations on all jewelry that is purchased in store; this helps us ensure your jewelry is secure and installed properly. We have a piercer on staff at all times who would love the opportunity to assist you. Be advised, we perform all of our piercing services on a walk-in basis. Wait times vary daily. All jewelry is final sale; no returns or exchanges unless there is a manufacturing error such as faulty pins or threads.
