Solid gold is durable enough for daily wear, including water exposure. For longevity, we recommend removing the ring during high-impact activity (weight training, rock climbing, manual labor) and avoiding direct contact with harsh chemicals including chlorine, bleach, and acidic cleaners. A soft-bristled brush and mild soap in warm water is sufficient for home cleaning. Complimentary cleaning, polishing, and inspection within the first year of purchase — see our Warranty & Repairs page for full coverage details.
