Here's a list of tips for you on how to care for your Astrid & Miyu jewellery. Avoid air contact when storing. Storing in our original boxes or pouches is the best way to keep your jewellery. A zip plastic bag is a handy way to do this in case you have lost the original packaging. Avoid water: Do not place next to heater, window, air conditioner or in the bathroom. Do not wear it in the pool or shower. Avoid cosmetics. Apply scents or cosmetics before you put on your jewellery. Perfumes and lotions will tarnish the jewellery. Avoid sweat. Remove jewellery when exercising, or any other demanding physical work, as sweating causes the jewellery to tarnish.
