How to Clean Coral Rings
The coral in real coral rings is made from the skeletal remains of coral, a type of marine animal. It is composed mostly of calcium carbonate. As such, coral is softer than many gems and is easily scratched. When cleaning these rings, you must be careful to avoid using abrasive substances. Acidic cleaners, even mild ones such as vinegar solutions, will start to dissolve coral and must be avoided. Does this Spark an idea?
