What Materials Are Used To Create Astrid & Miyu Jewellery?Updated 3 days ago

We’re all about quality, sustainability, and sparkle!

At Astrid and Miyu, we carefully select premium materials to create pieces that are as kind to the planet as they are to your jewellery box.

14k Gold

Our 14k solid gold is made from 58.3% pure gold, which means it's super durable, has that gorgeous warm golden glow, and is perfect for wearing day in and day out! Best part? Our gold is 100% recycled and 98% comes from Responsible Jewellery Council-certified suppliers! 

9k Gold

We use 9k gold in yellow and white for our permanent jewellery range - strong, durable, and oh-so-pretty. It’s made from 37.5% pure gold, and its soft, dreamy colour makes it perfect for pieces you’ll never want to take off! 

Sterling Silver

Our recycled sterling silver pieces are made from 92.5% pure silver and plated in either 18k yellow gold, 18k rose gold, or rhodium. We refine the silver to make sure it’s as high-quality as mined metal, while being kind to the environment! 

Plated Brass

For our bold, statement-making jewellery, we use plated brass. Brass is a durable and budget-friendly option. These beauties are plated in 18k yellow gold, 18k rose gold, or rhodium for extra shine and durability. Perfect for those “look at me!” moments! 

Pearls & Gemstones

Each piece featuring freshwater pearls or semi-precious stones is as unique as you are! Expect variations in shape, finish, and colour - but trust us, they’re all stunning in their own way. Our gemstones are all lab-grown have all the sparkle of natural stones but with a lower environmental impact

Every product page has a ‘Details’ section, so you can always check out exactly what materials are used in each piece.
