There was a time when engagement rings meant one thing: a traditional, earth-mined diamond in a classic setting. But times have changed—and so have preferences. More and more couples in the UK are ditching old norms and embracing something smarter, more ethical, and surprisingly stunning: the best lab grown diamond engagement rings UK jewellers have to offer.

At A Star Diamonds, we’ve had a front-row seat to this shift. What used to be a niche request has now become one of our most popular categories. And it's easy to see why.

What’s the Buzz About Lab Grown Diamonds?

Let’s be clear—lab grown diamonds are real diamonds. They share the same chemical and optical properties as natural ones. The only difference? They’re grown above ground in a lab using advanced technology rather than being dug from the earth.

What does that mean for you? A few key things, actually. For starters, lab grown diamonds are often 30–40% less expensive than mined ones. So, if you're working with a set budget but still want a show-stopping ring, you’re in luck.

Also, they come with a clean conscience. No mining. No environmental destruction. No questionable labour practices. Just a beautifully clear, high-quality stone that shines just as bright—if not brighter—than its natural counterpart.
