Do not swim, bathe, shower or exercise in your jewelry. This is very important not just for the metals but also because DNA is organic material and can mold with overexposure to moisture.
Do not apply topical products on it such as lotions, creams, powder, essential oils, household cleaning products, etc.
Take off when doing heavy chores, cleaning, gardening, or at the beach where small particles can get stuck in small crevices of your jewelry. Avoid prolonged, high intensity heat exposure.
Sterling Silver and Copper metals can tarnish. Follow proper metal care guidelines.
