Eternity rings are more difficult to resize than standard rings, so it’s important to get the size right from the start. We recommend using our free ring sizer (https://www.thediamondstore.co.uk/pages/free-ring-sizer-form) or measuring an existing ring that fits the correct finger. If you’re buying an eternity ring as a gift, try to borrow one of your partner’s rings in secret or ask a close friend or family member for guidance. Our customer service team can also help you choose the best size for a perfect fit.
Eternity rings usually can’t be resized because of their continuous band of diamonds or gemstones, so it’s important to get the size right from the start. If you’re unsure, our team is here to help with sizing advice and to confirm whether your chosen design offers any flexibility. And for extra peace of mind, our exchange policy makes it easy to swap for a different size - so you’ll always end up with the perfect fit.
A full eternity ring features diamonds or gemstones set all the way around the band, creating continuous sparkle from every angle. A half eternity ring has stones set across the front half of the band only, leaving the back smooth for added comfort and easier resizing. Both styles symbolise everlasting love, with the choice often coming down to personal preference and lifestyle.
Yes, our eternity rings are crafted with durable metals and high-quality diamonds or gemstones, designed for regular wear. However, because the stones sit across the band, we recommend removing your eternity ring during manual work, gym sessions, or when using harsh chemicals to protect both the setting and the stones. With the right care, your eternity ring will stay beautiful for a lifetime.
Eternity rings are traditionally gifted to mark life’s most meaningful milestones, such as anniversaries, the birth of a child, or any other significant celebration. You can wear them as part of your wedding stack, or on any finger you choose. The continuous row of sparkling stones symbolises everlasting love and commitment, making them a meaningful choice for marking a new chapter in your love story.
