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.
