Whether you prefer platinum, white gold or yellow gold, have you considered the pros of buying a lab diamond ring? At Miltons Diamonds, we stock an array of lab-grown diamond rings in various styles, including engagement rings.

What is a lab diamond ring?

As the name suggests, lab diamond rings have been created via a machine in a laboratory. The diamond used is identical to its natural counterpart and is classed as a diamond in every way. If you place a like-for-like lab diamond ring next to a naturally mined diamond ring, they’ll produce the same level of sparkle, so you’ll be unable to tell the difference. 

Discover more about how lab-grown diamond rings are made in our guide.

Where to buy lab-grown diamond rings

Though more people are searching for lab-created diamond rings, knowing where to look can be difficult. At Miltons Diamonds, we make buying lab diamond rings quick and simple, so rest assured knowing you’ll get quality from us. Everything in this range has been professionally certified and graded, following the same process as natural diamond jewellery. We provide a choice of metals, diamond colours and diamond clarities, allowing you to find the perfect lab diamond ring.
