Even the best lab-grown diamonds can stir up a bit of skepticism in shoppers—and for good reason. You might wonder: How can anything concocted in a laboratory compare to what’s organically found in nature? But with new technologies and sustainable practices, there are a lot of benefits to lab-created diamonds, which are very much “real.” Based on my extensive research, I determined the seven online retailers that offer the best lab-grown diamonds; my top pick overall is Blue Nile, which offers high-quality pieces at reasonable prices, along with complimentary ring resizing and polishing services.
The best lab-grown diamonds come from top online retailers that put an emphasis on sustainability.

Perhaps the biggest upside to choosing lab-grown is that there’s no mining involved, and many brands—including Vrai and Clean Origin—create these stones with renewable energy, leaving behind very little (or zero) emissions. To make my selections, I tapped into my own jewelry knowledge as both a fashion and gem expert; I also consulted with Ankur Daga, the founder and CEO of Angara, a leading online jeweler. In addition to recommending trusted retailers, I’ve selected standout pieces to buy—from timeless engagement rings to shimmering tennis bracelets—if you’re on the search for some sparkle.

Blue Nile has been around for over 20 years, so it’s a trusted authority in an otherwise newer space. All of its loose diamonds are analyzed and graded for quality by the Gemological Institute of America (GIA), one of the most accurate labs in the diamond industry. Since the brand sells direct to consumer, it’s able to offer high-quality stones with low overhead costs and, as a result, attainable pricing. In addition to rings, Blue Nile also offers a gorgeous selection of bracelets, earrings and necklaces—its simple studs earned the top spot on our list of the best lab-grown diamond earrings.
The brand provides plenty of opportunities for customization, so you can create a bespoke ring, pendant or earrings with lab-grown diamonds. For wedding rings, I love the French Pavé Diamond Eternity Ring; and for gifts, I’d suggest the half-carat diamond earrings or classic tennis bracelet. The prices are great and you get nice extras—like a free gift box and notecard with purchases.
Price range: Pieces start at $110 | Shipping and returns: Free shipping and returns within 30 days; full return policy | White-glove services: Free engraving for rings, prong tightening, re-polishing; real-time diamond viewing with expert gemologist online
Located in the diamond district in New York, James Allen carries both natural and lab-grown diamonds. The jeweler is best known for its massive selection of stones in every cut, at every price point—it has an excellent reputation for quality, service and expertise. Plus, it offers a virtual service for custom-made rings, and you can inspect your diamonds in real time, with a 360-degree view and advice of an in-house gemologist. Typically, if you shop for lab-grown diamonds, you can get up to 30% more size for the same cost—which really helps maximize your budget.

Stones are created in its zero-emissions diamond foundry, which is based in the Pacific Northwest and run on 100% hydropower. Leonardo DiCaprio is an investor in this forward-thinking jeweler, and all lab-grown diamonds come with certification that includes country of origin (not all brands offer this), along with a lifetime warranty.
Aside from preserving the environment, Vrai prides itself in hand-chiseled and polished diamonds by artisans. The attention to detail shows: Vrai’s diamonds have some of the best, sparkling cuts on the market. Some of my favorites include the knife-edge solitaire setting, solitaire studs and tennis bracelet. I also like how transparent the brand is about prices and policies, which are listed right on every product page.

If a comparable diamond in its inventory has a lower price from another jeweler, it’s price matched.
