Our jewelry is plated in 14k gold or rhodium over brass and is nickel-free. While it's designed to be durable, exposure to chemicals in water, lotions, or perspiration can cause tarnishing over time, so we recommend avoiding prolonged contact with these. You can keep your pieces looking great by buffing them with the polishing cloth included in your order. For 14k gold pieces, you can also scrub them lightly with a fresh toothbrush and warm water.
If you're ever concerned about your piece, our Shine On Protection plan offers a one-time replacement for any reason, including tarnishing, with no expiration. You can find more care tips here: https://www.bryananthonys.com/blogs/learn/how-to-care-for-gold-jewelry?_pos=1&_psq=care&_ss=e&_v=1.0
