When cleaning jewelry with soft stones such as opals, onyx, or pearls use Connoisseurs Delicate Jewelry Cleaner or Connoisseurs Dazzle Gel Quick Jewelry Cleanser + Brush and follow package directions. If the pendant doesn’t have prongs holding in the stone, it could be set with glue. In that case it’s more delicate. Wet the brush with the cleaner, don’t submerge the jewelry in the cleaner, and gently brush the jewelry and rinse off with water.

If your opal is set in silver, use Connoisseurs Dazzle Drops Silver Jewelry Cleansing Creme.
