Rubies and Sapphires
To clean rubies and sapphire jewelry at home, use a lukewarm solution of water and mild dishwashing soap, or one part ammonia to six parts water. Keep your gems brilliant by gently brushing them with a small bristle brush, especially underneath where dirt collects. Rinse and dry.
Like gold, platinum jewelry does not tarnish.
Simply clean your platinum pieces with a soft cloth and mild detergent or ammonia solution (one part ammonia to six parts water) to maintain their luster.
