As most of our pieces are costume jewellery made from sterling silver or brass, plated with 18ct rose gold, 18ct gold and rhodium, they need special looking after for you to enjoy the beauty for a longer period of time. Here’s a list of tips for you on how to care for your Astrid & Miyu jewellery.
-
Avoid Water
Do not place next to heater, window, air conditioner or in the bathroom. Do not wear in the pool.
-
Avoid Sweat
Remove jewellery when exercising, or any other demanding physical work, as sweating causes the jewellery to tarnish.
-
Storage
Storing in our original boxes or pouches is the best way to keep your jewellery. A zip plastic bag is a great alternative if no longer have the packaging.
-
Avoid Cosmetics
Apply scents or cosmetics before you put on your jewellery. Perfumes and lotions will tarnish the jewellery.
