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; plus, most of its lab diamonds come with reports from the International Gemological Institute (IGI), the leading grader for lab-grown stones. 

Since the brand sells direct-to-consumer, it offers high-quality stones with low overhead costs and, as a result, attainable pricing. In addition to rings, Blue Nile offers a gorgeous selection of bracelets, earrings and necklaces—its Round Brilliant Stud Earrings 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. Deputy editor Jane Sung and her husband purchased their wedding rings from Blue Nile and were impressed with the wide variety of styles and customization options, including engraving. Shopping at Blue Nile “made the whole experience feel approachable and helped us find bands that truly felt like us,” she shares. “I’ve been wearing my ring daily for over 12 years and still haven’t experienced noticeable damage or stones popping out.”

Editor picks: We love the Scalloped Pavé Diamond Ring for weddings; for special-occasion gifts, we suggest the Half-Carat Stud Earrings, the classic Tennis Bracelet or the gold Diamond Initial Pendant for layering. We also appreciate Blue Nile’s thoughtful extras, like a free gift box and notecard with purchases.

Sung is a fan of the brand for its affordability as well as “the variety of delicate, minimalist styles, including customizable charm collections, dainty rings and pieces that mix and match well together.”

We love the Birthstone Icon Pinky Ring above, which can be personalized with your birthstone, as well as the unique Diamond Pave Ear Cuffs and Lab-Created Diamond Push Pin Flat Back Studs for those with multiple piercings. Stone and Strand’s elegant tennis necklaces look equally stylish on their own or layered with other delicate pieces.

“Dorsey is known for its classic, tastefully designed jewelry featuring lab-grown gemstones,” says Sung, an almost-daily wearer of the brand’s rivière style. Rivière refers to single-strand jewelry with individual stones set in a continuous chain, and Dorsey’s version has become beloved by fashion editors, celebs and style-conscious consumers alike. They come in three different stone sizes, a variety of settings and chain lengths, and they’re available with different gemstones—including lab diamonds, lab white sapphires, moissanite and lab colored gemstones. The Kate style, which Sung owns, is most popular. “I have the Kate Rivière Bracelet, which is so timeless and still sparkles like new even after over a year of frequent wear,” she says. 

Editor picks: For an unexpected take on a tennis necklace, we love Dorsey’s Moss Riviere Necklace. It features delicate nano turquoise with a single lab diamond, and it comes in three different lengths. We’re also fans of the James Bezel Rivière Necklace featured above, which has a bezel setting.

Grown Brilliance sources lab-grown diamonds from trusted growers and sends them to a facility dedicated to its jewelry, where artisans customize each piece. In addition to engagement rings, you can also customize earrings, necklaces and bracelets, or you can shop the ready-to-ship pieces, including diamond studs, solitaire pendants and bangles. This expert customization is why the husband of Mackenzie Dillon, Forbes Vetted’s sleep and mattress editor, chose Grown Brilliance for her engagement ring. “We weren’t able to find the specifications I wanted in any jewelry store we visited,” she explains. They chose a Toi Et Moi Engagement Rings, where one stone is a radiant-cut diamond and the other is pear cut. “I absolutely love my ring. I’m often asked about my ring by strangers who praise its uniqueness and eye-catching sparkle,” Dillon says.

We love the convenience of being able to shop for both pre-set and custom-designed jewelry, especially if you don’t know where to start. If you decide to go the pre-set route, the brand partnered with wedding designer Badgley Mischka on a jewelry collection that’s truly one of a kind. Whichever avenue you take, Dillon says the entire process is straightforward and smooth. “From selecting the stones to delivery, it took around a month for my ring to arrive,” she says.

Editor picks: These Emerald Round Shadow Halo Studs, with a brilliant center, are a classic pick, and the vibrant gemstone color adds personality.

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 the advice of an in-house gemologist. These features are precisely why Molvar recommends James Allen as one of the best places to buy engagement rings. “Having tested the diamond jewelry myself, I love being able to see the rings from all angles,” she says.

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. Molvar also owns a gorgeous pair of James Allen lab-grown 14K White Gold Round Stud Earrings—“I can speak to the high sparkle factor,” she says. 

Editor picks: For engagements, the White Gold Petite Pavé Cathedral is one of our favorites, and we also recommend the Solitaire Diamond Pendant for subtle sparkle around the neckline.
