Unisex silver ring with holes and a melting effect. From TA's "Monster" collection. Handmade in Barcelona We work almost exclusively with sterling silver. With just a bit of routine care, silver jewelry will maintain its pristine appearance for generations to come. Over time, 925 sterling silver may darken, particularly when it interacts with products like perfumes, lotions, hairspray, salt, or anything containing sulfur. Oxidation rates can also vary based on the skin’s pH, which differs from person to person, but this is a natural occurrence, not a sign of poor craftsmanship. Restoring the original shine is simple: use a cloth designed for silver polishing, or gently scrub the piece with sulfur-free soap and a toothbrush, rinse well with warm water, and dry thoroughly. Skin interactions Sterling silver of the highest quality contains small amounts of copper. The interaction of silver items with the skin can sometimes leave marks. The factors influencing this are individual: temperature conditions, specific areas of the body, skin pH level, sweat, etc. This is completely normal for any silver products and is not harmful.
