To clean a semi-precious or precious gemstone, GIA recommends a mild detergent such as Dove liquid with slightly warm water then gently removing any debris with a very soft cloth or in some cases a very soft bristle brush. Organic gemstones such as Opal, Pearl, and Coral should be cleaned without the detergent using only warm water and a soft cloth.
