If you’re a fan of delicate jewellery, you’ll be pleased to know that Astrid & Miyu has brought back its popular opal collection. The brand’s designs are already popular amongst celebrities, with names like Jessica Alba and Victoria Beckham spotted wearing its pieces.

Opal jewellery is a perfect way to add a subtle flash of colour into your jewellery stack, without going too over the top. It’s just as suited to an everyday jeans-and-T-shirt outfit as it is to a more dressed-up look, and for that reason alone we’re big fans. With this collection, you’ll find a mix of pieces to suit all occasions, from delicate earrings and minimal bracelets, to more statement rings and necklaces.

If you’re already tempted to add something to your basket, there’s another reason to shop: from 27 August, you can get a free gift when you spend £120 at the jewellery brand, with even more to choose from if you spend £150.

The offer runs from 27 August (8am) until 1 September (10am), both online and in-store, or while stocks last. With a £120 spend you can choose from three gifts: the cosmic star charm bracelet, dome huggies, and pave twist detail huggies. A £150 spend unlocks a second selection, including the tennis chain bracelet, pave twist detail hoops and small horseshoe hoops. You’ll need to select your gift at checkout, and the offer can’t be combined with other promotions or discount codes.

Here are some of our favourite pieces from the collection.
