How to clean your opal jewelryYou can clean opal jewelry using a simple solution of non-abrasive dishwashing detergent and water. Add a few drops of palmolive, dawn or gentle soap to a cup of water and gently mix.. Swish the ring through the water and clean with a soft cloth. Any other stones on the piece can be cleaned with a soft bristle brush, like a baby toothbrush, avoiding the surface of the opal itself. By the way, opals like oils. If an opal dries out too much, it will crack. A good way to keep your Opal moist is to rub it against the side of your nose, or dab a little baby oil on it and then softly wipe it off. Make sure to not wipe too hard, you want the oil to absorb into the stone.
And as for tarnish on silver.... you can clean tarnish off silver with non-gel toothpaste and an old soft bristle toothbrush. Just scrub gently then rinse under running water while scrubbing with the toothbrush. After rinsing, set out to air dry. Or we like to use window cleaner. But be very careful with the opals. You don't want it to dry out. Make sure to put a little oil on it if you use either of these methods.
If the ring was expensive or is an heirloom, take the ring to a jeweler. A jeweler can remove the tarnish professionally.
Clean opal jewelry, especially rings, once every two months to prevent build up of skin oils and dirt. This will also make each cleaning process easier because less dirt will have accumulated.
Never place opal jewelry in an ultrasonic cleaner; the vibrations can crack the stone. In addition, traditional jewelry cleaning solutions can damage opals, so it is important to use the soap-and-water technique instead.
