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.

What our expert says: “What sets Blue Nile apart is the custom rings, pendants and earrings you can make with lab-grown diamonds,” says Molvar. “The prices are great and you get nice extras—like a free gift box and notecard with purchases. 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.”
