Opals are a type of gemstone that is often considered to be one of the most beautiful stones in the world. However, like any other gemstone, opals can become dirty over time. If you want to keep your opals looking their best, you’ll need to know how to clean them. To clean an opal, you’ll first need to remove any dirt or dust that may be on it. You can do this by using a soft cloth or a piece of sandpaper. Once the dirt is removed, you can use a mild soap solution to clean the opal’s surface. Make sure to rinse it off thoroughly before putting it back on your jewelry chain or setting it aside for later use. ..
