About precious metal Rhodium-plated silver - a coating with a thin layer of rhodium (a platinum group metal) protects silver items from blackening and allows them to retain their shine. The appearance of items with a rhodium coating is distinguished by a shinier and whiter surface., Silver - silver jewelry that has not been coated in any way has a natural appearance and color. Uncoated products have a moderate shine that increases with polishing. The lack of treatment mattes the surface over time, and oxidation is permissible on it. Silver is a universal metal that almost never causes allergic reactions. Among the disadvantages of uncoated silver jewelry is their darkening, which occurs over time, which can be eliminated by cleaning them, if necessary. size 5.5-9 ?2099871004
