Care Instructions

Solid gold and platinum naturally withstand water, oxygen, and chemicals, however, they can get scratched over time with wear. Silver is sensitive to chemicals, and its softness may cause it to bend if worn during workouts or cleaning. To increase your jewelry’s longevity, remove before doing any hard labor or cleaning with chemicals, like bleach. To clean your jewelry, gently scrub your jewelry with mild soap and water using either a soft brush or a soft cloth. For tough messes, you can soak your jewelry overnight in a cup of soapy water. Check out our Care Guide for more information.

Warranty

Automic Gold jewelry is made with durable, sustainable materials, hand-crafted by our expert jewelers, thoroughly inspected before shipping, and is backed by a limited lifetime warranty that protects against manufacturer defects.
