The best lab-grown diamond engagement rings for every style

Whether you’re planning on popping the question to someone special, or just want to know what your options are for when the time comes, our round-up of the best lab-grown diamond engagement rings includes a wealth of options for every style and budget. From classic styles to more unusual cuts and settings, we’ve included a selection of rings that cater to all styles and tastes.  


Before purchasing one of these stunning engagement rings, we recommend reading our essential guide to lab-grown diamonds first, which includes information about the pros and cons of buying a synthetic diamond, to find out if they’re the right option for you.  

There are many reasons why you might choose a manmade diamond over a natural one. They’re cheaper for one, making your dream engagement ring so much more affordable. Generally, they’re often a more sustainable choice, too. Most importantly, lab-grown diamonds don’t have to be mined, with some companies even using renewable forms of energy to mimic the conditions required to create a diamond.  

The one question that most people ask is: are lab-grown diamonds actually real? We’re pleased to confirm that diamonds grown in a laboratory are still 100% real, so you don’t have to worry that your engagement ring isn’t as prescious. It absolutely is.  

Ready to start your search? We’ve scoured some of the best ethical jewellery brands to find the most beautiful lab-grown diamond engagement rings on the market right now. Plus, to help make your search even easier, we’ve also picked out the rings we dub to be the best overall, from the best traditional engagement ring to the best-value engagement ring. 

Whichever you choose, we think every single one of these stunning engagement rings is impossible to say no to.

77Diamonds Principessa Solitaire  

Gold band solitaire ring

What: This gorgeous ring is made for timeless brides. With subtle teardrop detailing and a simple solitaire setting, you can’t get much more classic than this. It might not be the largest stone in the world, but what it lacks in size it more than makes up for in class. Besides, the simplicity of the ring is reflected in the price, with this being of the most reasonable options in our list.

VRAI Classic Pear Engagement Ring 

Pear shaped engagement ring

What: The best thing about VRAI is its bespoke engagement ring service, but if you’re not sure what you want, then this beautiful classic pear-shaped stone is sure to put a smile on any recipient’s face. The overarching style is classic, but the glitzy pave band adds extra detail and glam if you’re after a ring with wow-factor. The diamond is locked inside four subtle prongs, to allow the stone to shine through.

Queensmith Classic Oberon Engagement Ring

Oberon ring on hand

What: This ring is all about the glitz and glam! Featuring a spectacular scallop setting with a matching pave band, every millimetre is designed to sparkle.

Blue Nile Petite Twist Diamond Engagement Ring
