Mandala Crafts Yoga Meditation Tibetan Silver Tone Alloy Metal Ring Bohemian Tibetan Om Ring Made from White Metal Alloy Tibetan white metal alloy, also called Tibetan silver, is a copper based alloy metal. It is not sterling silver. White metal, copper, and brass will tarnish without polishing. The best way to treat the ring is to brush it with a toothbrush and some toothpaste. When the ring is dry after rinsing, please apply clear nail polish on the whole ring surface and it will not tarnish anymore. Because this is a handmade ring, it is not as spotless as a machine made ring. Imperfections due to the handmade nature may include: small dents and scratches on the metal surface, uneven colors, or cracks on stones.
