    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.

      Cosmic signet ring

      I absolutely love my new ring it’s so pretty and so shiny! I wish they did a better range of sizes though as the ring was either too small or too big for certain fingers but fits nicely on my ring finger

      The small details all over the band of the ring make the piece all that more special

      Amazing purchase

      This is my new favourite ring and I’ve had so many compliments on it. The staff in the Edinburgh store were really helpful in getting me to choose the right size!
