Caitlin has the best advice for this question: treat your jewellery like a silk dress. If you are wondering if you should take off a piece before doing an activity, ask yourself if you'd do it in a silk dress. If the answer is no, take it off. For the most part, you should take off your engagement ring before sleeping, bathing, cooking, or exercising. Working out can also cause your hands to swell, which may make it harder to remove your jewellery later on. As far as handwashing goes, be careful when applying sanitizers, as some may not be safe for delicate stones such as opals and pearls.
