Half or Full Eternity Ring? Lab-Grown Diamond Eternity Rings in the UK, with Prices
You want a ring that says the years mattered, in a style you’ll wear every day.
If you want lab-grown diamonds across the top of the band and a ring that sits comfortably beside other rings, choose a half eternity ring. If the unbroken circle matters most to you, choose a full eternity ring, with lab-grown diamonds set all the way round. Both are made to order; the right answer is the one that suits how you want to wear it.

How to choose a half or full eternity ring
Choose for the way you will wear it, not simply for the largest carat weight. Begin with the meaning you want, the rings it will sit beside and the amount you would like to spend. Then choose the metal and setting that feel right for you.
Choose a half eternity ring for an easy ring stack
A half eternity ring sets lab-grown diamonds across the top of the band only. It is often worn beside an engagement ring and wedding ring, and it sits comfortably alongside other rings. If your eternity ring will become part of an everyday three-ring set, this is the straightforward place to begin.
Lottie and Mabel give you two different total carat weights in the same half-eternity format. Both are available in 925 sterling silver or solid gold, so you can decide whether you want the lower starting price of silver or the colour and carat of gold that best matches the rings you already wear.
Choose a full eternity ring for the unbroken circle
A full eternity ring has lab-grown diamonds all the way round the band. That continuous setting creates the unbroken circle many buyers have in mind when they picture a full eternity ring.
Imogen uses round lab-grown diamonds for 1.62ct total, while Anastasia uses emerald-cut lab-grown diamonds for 6.00ct total. The difference is in both the shape and total carat weight, so decide whether you prefer round or emerald-cut lab-grown diamonds.
Choose the metal after you choose the style
Our eternity rings are made in solid 14kt or 18kt gold in white, yellow or rose, or in 925 sterling silver. They are UK hallmarked where required. If the ring will sit beside an engagement ring and wedding ring, choosing a metal colour that works with the rings you already own can help the set feel considered.
Whichever design you choose, every lab-grown diamond we set is D–F colour and VS1 clarity or better. Each ring is made to order in around four weeks, with free tracked and signed-for UK delivery and a 12-month guarantee.
Check your UK ring size before ordering
Every eternity ring is made to order in your exact UK ring size, so check the size carefully before you place the order. Our ring size guide explains how to find it. You can also order our strap sizer for £5, and the £5 comes back to you as a gift card.
