Choose a Lab-created Diamond Eternity Ring

arrow

Because what says everlasting love better than a sustainably made diamond ring? One that keeps the great sentiment, but ditches the fallout from traditional diamond mining. All our pieces are real diamonds, created in a lab rather than mined from the earth, that our designers have set into fully recycled 18k gold. A forever piece of jewelry, for a forever kind of world.

What are eternity rings?

First popularised in the 1960s, this style of diamond ring was designed to celebrate lasting love and an ongoing commitment between couples. The idea of ‘eternity’ is symbolised by a continuous row of diamonds on a band of precious metal. Enduring love, on an enduring and timeless piece of jewelry.

We wanted to pay tribute to this piece in our jewelry box, but naturally we’re giving it a signature Kimai twist. As well as switching things up sustainably with lab-created diamond eternity rings, we’re updating the memo. Whether you’re celebrating an anniversary or celebrating the love you have for yourself, we think a ring for all eternity suits whatever occasion feels right for you. Your life, your collection, you set the rules.

Styling your lab-made diamond eternity rings

The Lady is a rework of traditional eternity bands. With 12 diamonds made in a lab, plus a perle finish band, it catches the eye with its claw-set stones and intricate detailing. Plus, it’s made to stack. Team it with the Wonder ring for maximum impact and an update of what eternity jewels are all about.

Buy lab-grown diamond eternity rings with promise

When you choose a Kimai piece of jewelry, you’re choosing a sustainable, forward-thinking brand with an experienced team on hand at every step of the process. Because all our pieces are handmade in Antwerp, the home of fine jewelry, you can be sure you’re getting something exceptional, something truly crafted, and now of course, something that’s good news for people and planet.
