Lab grown diamond engagement rings

The most stunning engagement rings are Plum lab grown diamond engagement rings. Lab grown diamonds grace our fingers without trade-offs. They are friendlier to your planet, to your wallet — and we believe they make better jewelry, because higher quality and carat weights are so much more accessible in lab grown diamonds.

So if you're not into trade-offs, consider this simple fact: you get more bang for your buck when you buy a lab created diamond engagement ring. 

At Plum Diamonds, we back you up with the most exceptional craftsmanship and materials on the market. Our lab diamond engagement rings are made by Plum (no middleman - for real) and designed to enhance the beauty and shape of each diamond we set. Our facility has been certified by a 3rd party auditor to be aligned with stringent ethics and sustainability standards set by the global leader in responsible jewelry sourcing.

We'll help you get your hands on the ring you (or they) have been dreaming about. Based on years of experience, we’ve curated foolproof designs that are timeless and modern; for example options include a three stone baguette diamond engagement ring, pear side diamonds for an antique diamond engagement ring feel, and a half eternity band engagement ring for perfect simplicity. Available in all colors with a white, rose, or yellow gold band.

When you choose one of Plum's unique diamond engagement rings, you're getting a diamond as unique as your love story, handcrafted by us and hand-chosen by you. Shop our collection of lab diamond engagement rings today or contact us to find out how we can create the perfect ring for you.
