For all jewelry, take care of them in order for them to stay fine for a long time. Both genuine silver and other metals, with or without plating, can be damaged by cosmetics, skin lotions, hair sprays and other chemical products. Always remove the jewelry before you shower or bathe. Do not wear your jewelry when you are sunbathing or while sleeping. Take off rings and bracelets when washing or doing other housework. Keep in mind that rings with stones are sensitive. The best way to store the jewelry when you are not using it is in a small plastic bag so it is not exposed to air or moisture that can oxidize or discolor the jewelry. If the jewelry has become matte or darkened, it is just to clean up with a silver cloth or cleaning polishe like Hagerty or similar from the speciality retail.
