When I started as an editor at The Knot over six years ago, lab-grown diamond engagement rings were a glimmer on the radar of the jewelry industry. During my time covering wedding trends, I've witnessed their popularity surge firsthand. According to data from our 2024 Jewelry and Engagement Study, we found that over half of all engagement rings (52%, to be exact) featured a lab-grown diamond; a six percent increase from 2023. Our stats also found that the average engagement ring cost continues to fall, while the average carat size is slowly increasing. We can correlate this trend to the rise of lab-grown diamonds, which are generally less expensive than mined diamonds.
Lab-grown diamond engagement rings aren't just a fad. Thanks to their often lower price point, they offer a budget-friendly option for couples to get their dream engagement ring without over-spending. Of course, if you're deciding between different types of diamonds (like a lab-grown diamond or a mined stone), there are pros and cons to consider for both. Even though they're manufactured, lab-grown diamonds are chemically the same as mined diamonds. They tend to be less expensive than natural diamonds because the creation process is more efficient and cost-effective. Lab-grown diamonds don't have the same monetary value as natural diamonds over time, but if that doesn't matter to you, choosing one for your engagement ring can be a great choice, both in terms of cost and aesthetics.

Below are several trustworthy online retailers that sell lab-grown diamond engagement rings. Alternatively, if you prefer to shop in person, use The Knot Vendor Marketplace to search for jewelers that sell lab-created diamond rings near you.

Our Favorite Lab Diamond Engagement Rings
There are so many beautiful lab-created diamond engagement rings out there, and browsing through them to find the perfect proposal piece can feel overwhelming. We've curated a short list of editor-vetted lab-grown diamond engagement rings that you can shop right now.
Blue Nile Classic Simple Solitaire Engagement Ring

According to our data, ovals are one of the most popular engagement ring shapes right now. This timeless style from Blue Nile is as elegant as it is budget-friendly: Since the elongated shape of an oval can make it look larger than its actual carat size, you can opt for a "smaller" stone without sacrificing its sizable appearance.
Jean Dousset Chelsea Solitaire Lab Diamond Engagement Ring

Emerald-shaped diamonds are the epitome of quiet luxury. But since their internal step-cut facets show inclusions more clearly than a traditional brilliant cut, mined emeralds come with a significantly higher cost. One way to get the look (à la Sofia Richie) is to opt for a lab-grown stone. The Chelsea solitaire from Jean Dousset is a beautiful option. Customize the metal setting to be the color of your choice, and if you aren't feeling the squared edges, replace it with another fancy shape like an oval, marquise, pear or cushion.

We love this ready-to-ship lab-grown diamond engagement ring, which highlights a beautiful oval center stone perched atop a sparkly pavé band.
