How To Clean Your Semiprecious Stones Jewelry
Soak rings, bracelets, necklaces, and earrings in a solution of 1 cup hot water and and a little dishwashing soap and swirl it around for 30 minutes. Scrub around the stone’s settings with a soft toothbrush, then rinse under warm running water. (PSA: Close the drain first!) Pat dry. Repeat if necessary.
