Twenty-one pieces of diamond jewelry, a panel of seven testers, a physicist, a laser, a fireproof safe, and an eye-popping insurance policy—that's what we needed to pull off the Brides diamond testing and compile our list of the best places to buy lab-grown diamond jewelry.
Chemically identical to natural diamonds, lab-created diamonds offer all the sparkle at a more approachable price point. Plus, because they’re sustainably grown and ethically sourced, they’re an eco-friendly choice you can feel proud to wear. And make no mistake: Both are real diamonds, full stop. Unlike simulated diamonds, lab-grown diamonds have the same aesthetic, physical, and chemical characteristics as natural diamonds. The only difference? Lab diamonds are created in a controlled setting, while natural diamonds are mined from the Earth.
Under the guidance of Dr. Ulrika D'Haenens-Johanssen, an expert from the Gemological Institute of America (GIA), the Brides team tested 21 pieces of lab-grown diamond jewelry from 10 different brands in our New York City Lab. Our testers evaluated the appearance of each diamond, setting quality, fit, and presentation. Dr. D'Haenens-Johanssen used the GIA iD100 ® —a specialized instrument that separates natural diamonds from laboratory-grown diamonds and diamond simulants. "By eye, it's difficult to tell the difference between a lab-grown diamond and a natural diamond," she explained. Since natural and lab-grown diamonds are chemically the same, this method helps scientists, appraisers, and jewelers tell the difference and assess the quality of a stone.
When choosing a lab-grown diamond, you should still look for the four Cs: color, cut, clarity, and carat. As for size, because lab-grown diamonds are more affordable, you can get more carats for less cash. And at the end of the day, most people can't tell one from the other, so you'll still get that wow factor.
We compared a natural and a lab-created diamond from Brilliant Earth's collection and found it impossible to distinguish between the two with the naked eye. The brand's readymade engagement ring designs are classic, and the round-cut engagement ring we tested is the perfect option for a bride-to-be who wants a timeless look. If you have more modern tastes, you can design your ring by choosing a center stone and one of several setting options, from traditional solitaires to ornate three-stone shapes. (One of our favorites is the eclectic Versailles ring, which features a center stone adorned by smaller round and marquise cut lab diamonds.)
We love the choices available for the brand's lab-grown diamond studs. Our testers liked how the four-prong basket setting on the 3-carat studs let the brilliance of the diamonds shine through, while the double-grooved posts and guardian backings kept them firmly but comfortably in place. (One tester was ready to buy them on the spot!) Beyond rings and studs, Brilliant Earth also offers lab-created diamond pieces like wedding bands, tennis bracelets, hoop earrings, and pendant necklaces. Most jewelry options, including engagement rings, are available in four precious metal types: 18K white gold, 14K rose gold, 18K yellow gold, and platinum.
With all the customization options available, navigating the Brilliant Earth website can be overwhelming. It takes some searching to find the selection of lab-grown engagement rings, though the section of other lab-created diamond jewelry offers a super-enjoyable browsing experience. Overall, we were impressed with the quality and presentation of the jewelry we evaluated, right down to the natural wood jewelry boxes. And Brilliant Earth customers agree—the brand's reviews section is filled with 5-star feedback.

The Ritani lab-created solitaire engagement ring we tested scored high marks for the four C's. The stone was crystal clear with no discoloration, and the shape of the Princess-cut stone maximized its brilliance, with testers noting that it even appeared to have more detailed faceting than the natural Ritani diamond. And just like the other lab-grown diamonds we tested, you can get more carats for less cash, so don't be afraid to go big. If you're looking for a non-traditional ring, this is the place to shop. With its low profile center stone and diamond-studded band, the French-set diamond band ring is a conversation starter. Plus, the brand offers a stunning array of colored lab-grown diamonds in shades like blue, yellow, and orange.
Ritani's round stud earrings dazzled us too. The three-prong martini basket was an understated setting that made the earring perfect for everyday wear. We weren't impressed by the simple push backings, which one tester dropped as she put the earrings in her ears, but luckily, you can opt for more secure screw backs. There's also a wide selection of necklace pendants in heart, halo, and pear cuts.
Ritani is big on price transparency, providing details on the costs of creating each lab-grown diamond, such as fulfillment fees and markups. With lab-grown pieces starting at just $280 and loose stones starting at $75, the brand's jewelry is perfect for gifting a friend, family member, or fiancé—or treating yourself.
Price range: $590–$8,699
Special Services: Lots of customization options | Shipping and Returns: Free shipping and 30-day return policy (even for custom and engraved rings)
Samples of jewelry from Clean Origin were not available for testing. We decided to include the brand on our list based on research and editor knowledge.
Clean Origin caters to couples who want to create a one-of-a-kind engagement ring, with an easy-to-use customization process that includes a wide range of setting styles and diamond cuts. They have a special section of vintage-inspired rings, which include unique stone designs like a demi marquise halo and six precious metal choices. Each engagement ring comes with an extended lifetime warranty plan, annual jewelry inspection, repairs, and resizing.
The brand also has our favorite collection of lab-created diamond wedding bands—including the delicate and modern Danica band—bridal sets, and stackable rings. If you're looking to splurge on something special, check out the line of lab-grown diamond tennis necklaces. They're pricey but still thousands less than you'd pay for a collar made with natural stones.
Clean Origins has a fascinating story and a full-service philosophy. Founder Alexander Weindling left his family's natural diamond company to start the brand, which exclusively sells ethically sourced, eco-friendly lab-created diamonds. Each member of its customer service team must have a minimum of five years of experience in the industry to ensure that they can provide hands-on expertise and guidance.
Price Range: $750-$75K+
Special Services: Virtual appointments, lifetime warranty, payment plans | Shipping and Returns: 100-day return policy
Since they don't sell natural diamonds, 12FIFTEEN focuses on perfecting its lab-created jewelry. The Bare 6-prong round-cut engagement ring we tested was solidly constructed and felt substantial on our tester's finger. Since the stone sits higher in the setting, it looks great when paired with a wedding band. The box the ring came in looked a little cheap, so if you really want to make an impression when you pop the question, we recommend investing in a more stylish ring box.
The stud earrings were small and delicate, the perfect pair for a bride who doesn't want her jewelry to distract from her dress or anyone who wants diamonds they can wear to dress up a regular OOTD. Putting the backings on over the double-notched posts was challenging, but we appreciated that they kept the earrings perfectly positioned on our earlobes.
The brand also has some interesting takes on other styles of lab-created diamond jewelry, including the Luna Collection—signet rings representing the four different lunar phases—and on-trend initial pendants. Among Ritani's customer-forward policies is the "Trade Up program," which allows you to upgrade the diamond center stone on your engagement ring for a diamond valued at least twice the original value.
Price Range: $570–$8,720

We loved the angled shape of the band on the James Allen 1-carat Knife-Edge solitaire ring but were a little disappointed that the lab-grown diamond looked a little buried in the low-profile setting. Thankfully, there are 14 different head styles to choose from–and plenty of other customization options—available in The Ring Studio.
The four-prong stud earrings we tested were petite but still delivered a dazzling effect, the perfect pair for someone who prefers their jewelry to be subtle and subdued. Standard friction back posts come with the earrings, or you can upgrade to screw backs for an additional $125—a worthwhile investment if you frequently lose earrings.
James Allen specializes in both conflict-free natural stones and lab-created diamonds. The brand's website features the brand's proprietary Diamond Display Technology. This game-changing, 360-degree feature lets customers view stones through a virtual jeweler's loupe and takes much of the guesswork out of shopping for a diamond online.

This year, VRAI and Brides collaborated to create the VRAI x Brides collection of fine jewelry pieces. In our lab test, we examined and evaluated jewelry from the brand independent of the partnership.
If you're a minimalist at heart, you'll fall in love with VRAI's line of lab-created diamond engagement rings, as we did. The classic solitaire ring we tested passed the GIA standards test and enchanted our group of testers, who loved the elevated aesthetic and the relatively low price point. The stone was perfectly colorless and clear, and the simple setting let it take center stage. The sample we reviewed was a classic style, but the brand also offers unexpected designs like the Hover ring, which features a floating stone in a cup setting.
Even the tester who held firm that she'd still prefer a natural diamond engagement ring over a lab-grown option admitted she couldn't tell the difference between VRAI's lab-created piece and an Earth-mined diamond ring when comparing them. The same tester was convinced that VRAI's lab-created diamond solitaire studs would be an excellent investment, noting how expensive and dimensional the stones looked (and felt). We're also impressed with the brand's other earring styles, which include V-shaped studs, pavé bars, and the Shooting Star ear climber.
You can shop guilt-free, knowing the brand's diamonds are sustainably grown in their zero-emission foundry in America. Engagement rings are shipped in sustainable packaging and can even be set in recycled gold. "There is complete transparency with our jewelry and sustainable diamonds, which are grown utilizing renewable energy," says VRAI CEO Mona Akhavi. "So there are no questions about origin or middlemen markups."

Millennials think differently about all aspects of engagements and weddings, eschewing the traditional for new ways to mark the occasion. So we were surprised when one 20-something tester was so impressed by the quality and origin story of the Grown Brilliance lab-created pieces she was ready to invest in diamonds for the first time in her life.
We'd change one thing about the pre-designed cushion-cut ring we tested—the high prong setting covered part of the stone's face, detracting from its full brilliance. If you want the diamond to get all the attention, we recommend opting for a halo style with prongs that aren't as noticeable. The stud earrings were a big hit with all our testers, with gorgeous martini-set stones and guardian posts to hold them comfortably in place.
Grown Brilliance is one of the few brands offering lab-grown pieces from well-known designer label Badgley Mischka. (Our favorites from the collection are the stunning oval engagement ring and the Graduated Riviera necklace, which gave us major Princess Grace vibes.) There's also a Red Carpet collection, which includes celebrity-inspired rings.

Consider the Wldflwrs
It's a challenge to find lab-grown diamond jewelry options on the Consider the Wldflwrs website, but it's worth searching to find signature pieces like the Oval Eternity band. Surrounded by dazzling stones, this rock-star statement piece is a bold alternative to a traditional solitaire. Available in seven metal options, it captivated our testers, who imagined a trend-setting bride wearing it as part of a bridal ring stack.
The classic diamond studs felt more appropriate for everyday wear than special occasions. We liked the martini-style settings but found them more expensive than lab-grown diamond studs from many of the other brands on our list. (A pair of studs set with 0.2-carat stones is more than $700, and if you size up to a full carat, you're looking at a price tag of over $2,500.)
The brand's ready-to-ship engagement rings all feature earth-mined stones, so if you've got your heart set on a lab-created diamond, you'll work with the director of bridal sales to design a ring. The process involves virtual consultations, sketches, and 3-D models, so while you'll need to budget extra time—production takes six to eight weeks from start to finish—you'll get exactly the ring you want.
Price Range: $374-$6,128

You won't find any rocks here. Still, the brand's limited selection of lab-grown diamond jewelry includes (under)statement pieces created using the same materials and manufacturers used by the world's most famous jewelry houses. The eternity band and solitaire bezel ring are diminutive but perfect for stacking and a solid buy for anyone on a budget.
The brand's Dalton round brilliant diamond studs sit atop a basket setting, which made them appear to be floating on the tester's earlobes, impressing us with their kaleidoscopic refraction of the testing studio lights. The set arrived in an illuminated box, making a great first impression. Some of the adjectives testers used to describe them include "luxurious," "modern," and "very expensive-looking." They're available in 4-carat weight sizes and come with screw-back posts.
Italic's motto is "luxury without labels." If you're intrigued by the idea of lab-grown diamonds but are still deciding whether to make a major investment, this is the place to start.
Price Range: $510-3,850

Samples of jewelry from Blue Nile were not available for testing. We decided to include the brand on our list based on research and editor knowledge.
Since launching in 1999, Blue Nile has become one of the world's most trusted online jewelry retailers, and that reputation extends to their selection of lab-created diamond jewelry. Made in partnership with Lightbox, the collection includes build-your-own solitaire engagement rings. Select the carat weight, color, cut, and clarity (or set a price range), and the website filters setting styles to suit your stone choice.
If you want a ring that's ready to ship, browse the brand's non-traditional options, including the Bypass ring, which features one round and one princess cut stone—the princess cut lab-created diamond can be traditional white, pink, or blue. Other lab-created diamond pieces include pendant necklaces and tennis bracelets, and we can't take our eyes off the lab-grown pink and white round cluster earrings.

Our experience with the Miadonna pieces triggered some kind of Goldilocks effect. Our testers thought the 1-carat diamond stone in the Tracie engagment ring looked too big set against the tapered cathedral band. Still, the diamond was mesmerizing, and you can choose the stone size that suits your taste. (It's important to remember that bigger isn't necessarily better when it comes to choosing an engagement ring.)
On the other hand, the lab-created diamonds in the basket stud earrings we tested seemed too small, so we'd suggest sizing up—which is easy to do with the diamond stud upgrade program. Choose the diamonds that fit your current style and budget, then trade them in for a larger stone size when you're ready. The brand will apply the original purchase price toward your upgraded pair.
The website's "build your ring" process is glitchy. Filtering the stone options takes time to load, and you don't get to see a photo of the ring with the customizations you've chosen before you check out. The head options are limited to four and six-prong styles, but you can choose from seven metal options—yellow, white, or rose gold in 14k or 18k, and platinum. We love the concept of the brand's home try-on program—they'll ship four sample rings to you so you can have a hands-on experience finding your favorite.

Helzberg's Light Heart lab-created diamond jewelry collection sits alongside the century-old jeweler's natural diamond capsules from designers like Zac Posen and Jenny Packham. So when it came time to test, we called in both grown and earth-mined engagement rings. One eagle-eyed tester could only tell the difference by examining both pieces with a magnifying loupe, which revealed a slight inclusion in the natural stone. Once she'd slipped the lab-created Prima Donna ring on her finger, she was swept up by the same sparkle and glamor that the natural diamond ring delivered.
Like the ring, our testers agreed that the stud earrings looked and felt high-quality and exhibited the timeless design hallmarks that distinguish a piece of heirloom jewelry. The princess-cut stones were perfectly matched and just big enough to turn heads without overwhelming the eye of the beholder. The screw-back posts provided reassurance that the delicate studs won't fall out if, say, they get caught in the fabric of a knit dress as you pull it over your head. (It's happened to us.)
There's a reputation for quality—and a great story—behind the Helzberg brand. Fun fact: The brand ordains its sales associates just in case engagement ring clients decide to elope inside one of their stores.
Price Range: $199-$10,999

How to Shop for Lab-Grown Diamond Jewelry
Like any significant investment, when shopping for a lab-grown diamond engagement ring, it's essential to research before buying. (Our vetted list is the best place to start!) Most trusted retailers will have an in-depth FAQ page highlighting how and where their lab-grown diamonds are made, how customers can choose their perfect stone, and details on certification, shipping, and return policies.
Since lab-grown diamonds share the same optical and chemical properties as natural diamonds, they are graded on the same scale of cut, clarity, color, and carat weight as natural diamonds. Lab-grown diamond engagement rings are also offered in scores of different styles, settings, and metals to suit all aesthetics. While many lab-grown options are less expensive than their natural counterparts, you can still pay a significant amount for a piece, depending on the quality of the stone and its setting. Lab-grown diamond jewelry can range from under $500 to over $70,000, depending on size, quality, and setting type. Once you've found your dream lab-grown diamond engagement ring, you should receive and review its lab certification.
How We Tested
To find the best places to buy lab-grown diamond jewelry, the Brides team spent hours researching the top lab-grown diamond companies, evaluating quality, range of styles, customer service, shipping and return policies, and overall value. We also interviewed leading gemologists and jewelry experts to get their insights on the differences between natural and lab-grown diamonds and tips on choosing pieces to suit any style and budget.
Then, the Brides team welcomed Dr. Ulrika D'Haenens-Johanssen, a research scientist from the Gemological Institute of America (GIA), to our New York City Lab, where she walked us through lab-grown diamond production and the differences (and similarities) between lab-grown and mined diamonds. She used a diamond reading device to inspect the pieces called in from various retailers. She also helped guide our hands-on evaluations and comparison of lab-created diamonds with natural stones.
"The machine can detect a spectrum of color that we cannot see with our eyes, and it analyzes that data," said Dr. D'Haenens-Johanssen. “The device looks for an unnatural signature, which means it is a natural diamond." The device can detect slight inclusions of particles that are only present in mined diamonds. "A strong UV light of a specific wavelength is emitted through the probe, which can detect atomic structural differences unique to each diamond through growth and history." Lab-grown diamonds don't have those tiny imperfections.
Brides editorial staffers tried on the lab-grown diamond pieces and compared them to naturally mined diamonds. We asked our editorial testers for feedback on things like first impressions, purchasing intention, knowledge of the jewelry brands, and their perspective on what consumers—both brides and lovers of diamond baubles—would think of buying or receiving a lab-grown diamond. "I'm a fan of lab-grown diamonds because they're more affordable," said tester Jessica Chassin. "It seems like you can't distinguish between a natural and lab-grown diamond from the naked eye.
Staffers tested stud earrings and eight solitaire engagement rings from 10 different lab-grown diamond brands. Three traditionally-mined diamond rings were on hand for comparison.
Most lab-grown diamonds are sustainably grown and ethically sourced, making them an eco-friendly choice you can feel proud to wear. When first introduced to the market, lab-grown diamonds were thought of as facsimiles of natural diamonds. Today, jewelry made using lab-created diamonds is more popular than ever and available in an endless array of styles, shapes, cuts, and settings. "At the start of testing, I kept mistakenly saying that I couldn't tell the difference between the lab-grown diamonds and the "real" [natural] diamonds," said tester Bronwyn Barnes. "After hearing the GIA scientist explain that lab-grown diamonds were real diamonds, it sunk in that the only major difference between lab and natural diamonds is the process by which they are made."
What is a lab-grown diamond?
Lab-grown diamonds are human-made stones created in a lab, formed using high-tech equipment that produces the same high pressure, heat, and chemical conditions it takes to create a natural diamond. We spoke to leading experts in the field to get their insights.
“Laboratory-grown diamond growth utilizes technology and machinery to create diamonds in as little time as a few weeks,” says Wade Abel, Director of Gemological Services at the American Gem Society (AGS) laboratories, an independent organization that provides third-party, expert evaluation of all types of diamonds. “Natural diamonds take hundreds of millions to billions of years to grow deep in the earth’s mantle and are only accessible once they are pushed up through rare volcanic activity.”
Despite being nearly identical to natural diamonds, gemologists can use specialized equipment to identify them. “Natural and laboratory-grown diamonds form under very different conditions, so, even though they look the same, there are characteristics that experts can use to separate them,'' said said Barbara Harwick, Senior Instructor at the Gemological Institute of America (GIA), one of the world’s leading educational institutes for the study of diamonds. But the variations in growth patterns and structure are hard to spot with a regular jeweler’s loupe or microscope, she explains. “You need expertise and advanced instrumentation to tell the difference.”
Lab grown diamonds are measured and evaluated using the same rigorous methods as natural diamonds. “Like mined diamonds, lab-grown diamonds come in a variety of sizes, as well as cut, color, and clarity grades. Luckily, the same GIA grading scales are used for both mined and lab-grown diamonds, so it’s easy to compare the two," Lisa Rosen, CEO of the International Gem Society (IGS), a gemological membership society for professionals and enthusiasts.
Are lab-grown diamonds real?
Yes! A manufactured diamond is as real as one that’s mined from the earth and has the same chemical and physical properties as a natural diamond. “Lab-grown diamond technology has gotten so good that most jewelers can’t tell the difference between a lab-grown and mined diamond using the naked eye,” said Rosen. “A loupe won’t even suffice— a jeweler would need sophisticated (and expensive) testing equipment to distinguish a lab-grown diamond from a mined diamond.”
As implied in its name, a lab-grown diamond is made using technology that simulates the conditions under which a natural diamond is created. “Natural diamonds formed billions of years ago deep in the earth under tremendous heat and pressure, and came to the surface millions of years ago,” said Harwick. When it comes to lab-grown diamonds, she explained there are several different ways that they are produced. “One process mimics the high temperature and high pressure of the earth to create the diamond,” says Harwick. “Another method builds up the rough diamond layer by layer.”
And as for the results? Though the laboratory process only takes a few weeks, it produces a gem that’s virtually indistinguishable from a diamond that took more than a billion years to form. “This technology is improving quickly, making it possible to produce larger, higher quality laboratory-grown diamonds,” said Abell.
However, there tends to be one noticeable difference between mined and lab-grown diamonds: price. "Lab-grown diamonds are a great choice for keepsake jewelry and engagement rings, because you can usually get a larger and better quality stone for a lower price," says Rosen.
What are the benefits of lab-grown diamonds?
While lab-grown diamonds can still be pricey, most are available at a fraction of the cost of a natural diamond. “"Consumers who used to be intimidated by the cost of natural diamonds now have many comfortable lab-grown options, said Avi Levy, President of the International Gemological Institute (IGI), North America, a global education resource and grading laboratory. "They’re available for prices far below their natural diamond counterparts, which helps stretch budgets. Couples may not have to choose between a big diamond and a big honeymoon.”
Diamonds made in pristine conditions in a lab don’t contain dirt or other impurities and have fewer defects. They are also considered to be more ethical than natural diamonds, since they are not mined, a practice that can be harmful to both the environment and the tradespeople who mine them. “If you are socially conscious–and many more buyers are these days–the only way to guarantee that you are getting an ethically-sourced diamond is to buy a lab-grown diamond,” says Rosen. She adds: “Traditional mining can have a negative impact on soil quality, wildlife, biodiversity, and fresh water. In addition, mining diamonds requires the use of fossil fuels like diesel, which generates greenhouse gas emissions.”
However, it’s important to note that lab-grown diamonds still have some environmental impact. “Despite some marketing claims, many lab-grown diamond producers do not run sustainable or eco-friendly operations,” said Levy. “These gems require enormous energy to grow and most are produced with the burning of fossil fuels. There’s a growing niche of producers who are committing to hydro, solar or wind power, so (rare) ‘sustainable’ lab-grown diamonds do exist.” If environmental impact is an important part of your decision, Levy recommends asking the manufacturer for proof of sustainability to back any claims.
How can you tell a piece of lab-grown diamond jewelry is worth the price tag?
“The most important thing is that the consumer works with a knowledgeable jeweler,” says Abel. “All laboratory-grown diamonds must be disclosed as such, and the retailer should be able to explain what a laboratory-grown diamond is and the differences and similarities between it and a natural diamond.”
Abel adds that transparency is key. “An ethical retailer will disclose all that is required (and more). Some retailers are members of nonprofit industry organizations, such as the American Gem Society, that must uphold specific standards to become members and retain their membership. You can inquire if your jeweler is a member of AGS, or visit ags.org/findajeweler to find one near you.”
It’s important for consumers to research and shop around before making a decision, says Rosen. She adds that the price range on jewelry varies based on the size of the stone and the setting, but that lab-grown diamonds tend to be significantly cheaper than mined diamonds. “This is due to the decrease in production costs, which allows lab-grown diamonds to be created at scale.” Rosen says that, in general, a lab-grown diamond usually runs about 50 percent less expensive than a mined diamond.
However, the pricing can vary widely, based on the diamonds themselves and their settings. “Certain classes and categories of lab-grown diamonds are starting to command premium prices,” says Levy. “As long as lab-grown diamonds continue to gain in popularity, the range of new options available to luxury, fashion and bridal shoppers is likely to keep growing.”
Abel adds that several factors can increase the diamond’s quality, rarity, and ultimately the price. "The less color that is present in a diamond, the less noticeable the inclusions, the higher the precision of the cut, and the size are all factors."
On the contrary, as the lab-grown diamond industry expands, Abel said that there could be shifts in price and value: “As more and more laboratory-grown diamonds are produced, they become less rare, which is a factor in the cost. Historically, this was seen with other laboratory-grown gemstones, like ruby, sapphire, and emerald, where the price dropped, and value is not near what it is for the natural counterparts.” This is important to consider if you're looking for a diamond as an investment item that will appreciate in resale value over time.
