Love & Strength

Diamonds really are your best friend. Known for being a symbol of love, it’s also the strongest of stones, meaning that it’ll never leave your side.

Pendant size: 2 x 3mm

Weight: 0.07g

Our solid gold pieces are made to be worn all day, every day. Made from 9k, 10k & 14k solid gold, they’re jewels you can depend on.

  • Gently clean

    If you find that your pieces are losing their shine, use the polishing cloth enclosed, or soap and warm water, to bring them back to life.

  • Storage

    The best place to keep your jewels is in their original jewellery box, or in an air-tight bag to keep them protected.

Our charms are designed to help you create jewellery that's as unique as you are, but not every charm fits every style. To help you find your perfect pieces, we’ve put together a Charm Compatibility Guide so you can build your dream stack without the guesswork.

    Diamond Chain Charm

    Had this beautiful chain charm made in the Carnaby Store. Such a lovely personalised experience which I really enjoyed, and the perfect addition to my Astrid & Miya Cosmic star flat back. I love it and have had so many compliments

    So sparkly I love it

    I got the welded bracelet with 3 charms and I’m obsessed with it. The diamond is sparkly and very pretty - and the bracelet itself is very small, simple and elegant I love it!
