This is a pendant from the Affinity collection designed by Christine Sadler.
This collection has rings that can be engraved and added to a necklace. You can buy the chains and rings individually to make your own unique combination and you can add rings at any point. This means that the necklace can become a sort of diary of all the things you love throughout your life.
This particular combination is a 9ct rose gold ring and a silver ring on a silver chain. Each gold ring is £100, each silver ring is £40 and the chain is £30.
The rings measure 10mm in diameter and the chain is 1.6mm wide by 45cm long but it is available in other lengths and styles.
