We’ll be the first to admit there's something undeniably special about natural diamonds (after all, they truly are a girl's best friend). But if you’re looking to get comparable sparkle out of your jewelry while saving a good chunk of money, you may want to go the lab grown diamond route.

Lab grown diamonds, which have surged in popularity in recent years, can be thousands of dollars cheaper than their natural counterparts—essentially since they’re considered "less rare." Yet unlike simulated diamonds made from moissanite or cubic zirconia, lab grown diamonds are, indeed, very much real.

"Lab-grown diamonds are exactly the same on the molecular level as mined diamonds," explains Meg Strachan, founder and CEO of emerging lab-grown diamond brand Dorsey. "Diamonds deemed ‘rare’ in mined terms can be created in lab-grown form that are just as beautiful as their counterparts and will cost much less. The ability to create diamonds and gemstones in the laboratory also means any color, cut, and clarity can be achieved," she adds.

Adding to their appeal, lab grown diamonds may be a more ethical alternative to mined diamonds—an industry that's notoriously been linked to the use of child labor and fueling conflict in war-torn areas. And thanks to innovations in technology, many brands making lab grown diamonds are doing better for the planet by minimizing or entirely eliminating their carbon emissions.

With all this in mind, we took it upon ourselves to curate a list of the best places to buy lab grown diamond jewelry in 2023. From gorgeous engagement rings in all shapes and sizes to an array of timeless baubles, these brands have tons of stunning pieces that make great graduation gifts, anniversary gifts, or fabulous treats for yourself.

Sherman explains that lab grown diamonds are created in a laboratory through one of two processes: High Pressure/High Temperature (HPHT) or Chemical Vapor Deposition (CVD). "HPHT replicates the natural formation of diamonds by subjecting carbon to high temperatures and pressing it together," he says. "In CVD, a seed crystal chamber is filled with a mixture of hydrogen and methane gas, and the diamond grows on the seed crystal."

"These chemical reactions allow a diamond to grow in a matter of weeks rather than thousands of years," continues Lisa Rosen, CEO of the International Gem Society, a leading resource for gem professionals. "CVD is a more popular process for producing gem quality diamonds, while HPHT is more common for producing diamonds for industrial uses."

"It is nearly impossible for the naked eye to tell the difference between a faceted lab grown diamond and natural diamond," says Rosen. "The only way to tell the difference is with very powerful and expensive lab equipment, which most independent jewelers won't have in their store."

"Lab grown diamonds are probably better for the environment, but they aren't perfect," notes Rosen. "On the one hand, there is no mining involved, so the negative environmental and biodiversity impacts from mining are avoided. On the other hand, it is extremely energy intensive to re-create the high-temperature, high-pressure environment needed to grow a diamond. Some lab-grown diamond producers claim to use renewable energy to grow their diamonds, so if a consumer is concerned about the environmental footprint of their diamond, they should buy from one of those producers."

Both Rosen and Strachan agree blanket statements shouldn't be made about all lab grown diamonds, but note that they can be a more ethical option, too. "Lab grown diamonds have found a large market with consumers concerned about illegally-traded ‘conflict diamonds’ used to finance wars or ‘blood diamonds’ mined with forced labor," says Rosen, who points to Russia's continued invasion of Ukraine as a cause of these growing concerns. "Russian-owned diamond mining company Alrosa makes billions of dollars in revenue each year from its diamond mines, and that revenue is supporting a Russian economy buckling under global sanctions. While many large retailers like Tiffany's have announced that they won't buy diamonds cut from Alrosa diamond rough, the lack of transparency in the diamond supply chain and loopholes in sanctions specifically related to diamonds and gemstones means it is difficult to guarantee that a diamond wasn't mined in Russia. Now, consumers know the only way they can avoid buying a conflict diamond is to purchase a lab grown diamond."

Sherman adds that all lab-grown diamonds are laser engraved with a serial number, making it "possible to know with certainty where each stone came from."

"Lab grown diamonds are graded exactly the same as natural diamonds using the 4Cs: cut, color, clarity, and carat weight," explains Sherman. "Cut doesn't refer to the diamond shape, but determines how well the diamond captures and refracts the light to produce that brilliant diamond sparkle. When looking for the perfect diamond, you actually want to look for the one with the least amount of color. The normal color scale runs from D to J, from colorless to near colorless, so the closer to D the more valuable the diamond. Clarity refers to the flaws or inclusions on and within a diamond. Flaws can impact the stone's ability to let the light pass through, so the fewer flaws, the more brilliant the sparkle. Carat refers to the diamond weight, not the size. Remember, however, that a high carat doesn't always equate to a better, sparklier diamond if said diamond is not well-cut."

Of course, the higher quality the diamond, the more expensive it will be—so always factor in your budget. Ask yourself a few questions, Sherman advises: "Does size matter most? Does scintillation? Are you willing to sacrifice a small tint in color for a larger stone? While the 4Cs can provide you with general guidelines, it's important that you know what you want and what choices you’re willing to make to find your perfect diamond."

Rosen also suggests there's a "5th C" to consider: "Make sure that any diamond you purchase comes with a grading report," she says. Trusted gemological institutes like the GIA and IGI have certification labs that grade qualities such as the color and clarity of lab grown diamonds to help inform shoppers’ purchases.

Additionally, keep in mind the setting of the jewelry. "Pay attention to the metal the lab-grown diamond is set in, such as 14kt gold, to ensure the piece lasts a lifetime," says Strachan. Finally, remember that "each cut speaks to a different personality trait and style, so it's key to understand those before purchasing a diamond for yourself or a loved one," advises Rosen.

"Due to the rapid decline in the cost to produce lab grown diamonds combined with the growing supply of them, lab grown diamonds will not hold their value as well as a natural diamond," says Rosen. But if you’re thinking of buying natural diamonds in the hopes of reaping a profit on them later, you may want to re-consider. "Natural diamonds rarely appreciate in value, and it's unlikely that a consumer will recoup their original purchase price on them," Rosen warns. "This is true even if the stone is appraised for the same or more than the purchase price."
