Jewellery Care & Materials

As most of our pieces are costume jewellery made from brass, plated with 18ct rose gold, 14ct 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 it in the pool or shower.


Avoid sweat: Remove jewellery when exercising, or any other demanding physical work, as sweating causes the jewellery to tarnish.


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.

Our Materials


Sterling Silver

925 Sterling silver is an alloy of 92.5% pure silver and 7.5% copper. We plate our pieces in 14k yellow gold, 18k rose gold and rhodium or leave it as pure sterling silver for its natural colour. We recommend that you keep your pieces away from water, sweat and cosmetics, and keep them in a tightly sealed plastic pouch so their beauty will last much longer.


Plated Brass

Brass is the most commonly used base metal used by luxury fashion houses to produce their costume jewellery due to its malleable characteristics. Think Chanel and Dior. We plate our pieces in 14k yellow gold, 18k rose gold and rhodium and black rhodium. Plated brass pieces will, unfortunately, tarnish over time. However, if you keep the pieces away from water, sweat and cosmetics, and keep them in a tightly sealed plastic pouch their beauty will last much longer.


Diamonds

Diamonds are one of the most durable and longest lasting natural substances found on earth, therefore commonly used as a promise for eternal love. Our high quality pave diamonds are ethically sourced from our trusted suppliers who follow ethical guidelines.


Pearls

We use cultured or farmed pearls that follow ethical guidelines. We’ve incorporated a fresh and trendy take on all our pearl designs so enjoy!


Cubic Zirconia

Cubic zirconia is one of the highest quality replica of natural diamonds, and sometimes clearer and brighter than natural diamonds.
