The famous slogan "A Diamond Is Forever" may have launched way back in 1948 (and diamonds are still the go-to gem for engagements) but an increasing number modern couples are opting for lab-grown diamond rings. According to The Knot 2021 Jewelry and Engagement Study, which surveyed over 5,000 engaged couples, 86% of engagement rings include a diamond center stone. The same survey also found nearly one in four of respondants purchased an engagement ring with a lab-grown center stone. TLDR; Lab-grown diamonds aren't just a passing fad, these high tech stones are here to stay.

Since their introduction, lab-grown diamonds have disrupted the way consumers approach diamond engagement rings for a few reasons: cost, environmental impact and ethical sourcing. Due to the rare and pricey nature of mined diamonds (depending on its quality, the average 1 carat natural diamond can cost anywhere from $2,000 to $25,000), opting for a natural stone can be cost prohibitive for those on a tight budget. Lab-grown diamonds, however, aren't nearly as expensive to create, and can cost anywhere from 20% to 50% less than their natural counterparts. Lab created stones also appeal to those searching for eco-friendly and ethically sourced jewelry. As the name implies, lab-grown diamonds are created by scientists and not mined from the earth, meaning they are always 100% ethically sourced and can have a smaller (though usually not invisible) carbon footprint.

Tips for Buying a Lab-Grown Diamond Engagement Ring

Similarly to buying a natural diamond ring, there are several factors to consider before you purchase a lab-grown sparkler—it's a big investment, after all. Below, a breakdown of expert tips for buying a lab-grown engagement ring.

Do your research. Start shopping with all of the relevant information and make sure you know exactly what you're buying. "It's important to know what you or your partner wants, learn the 4C's, search online and in-person, choose the retailer or designer that fits you best, and purchase a stone with an authentic gemological grading report," says Avi Levy, President of International Gemological Institute (IGI). "A grading report from IGI, the world leader in lab-grown diamond grading, will ensure that the quality of the stone has been verified by a third party and all the necessary testing has been performed. "

Opt for Better Clarity and Color. Diamonds are graded according to the 4C's: cut, clarity, color, and carat weight. Typically, the better a diamond's grade in these categories, the higher its price. Given that lab-grown diamonds cost anywhere from 20% to 50% less than natural diamonds, you can use your savings to buy a higher-quality stone. " I recommend couples stay within the F to G color range—stones graded with these colors are well-priced and will look very white in both yellow gold and white gold or platinum settings," says Shahla Karimi, the New York-based designer of Shahla Karimi. Where clarity is concerned (read: how heavily included or flawed a diamond is), couples should look for a stone with a grade of VS2 or higher, according to Josh Sherman, Director of Marketing & Branding at Grown Brilliance.

Consider Sizing Up. If your budget allows, you can also use your savings to buy a larger stone. The option to go bigger at a much lower cost is one of the main draws of lab-grown diamonds for many couples, especially now that solitaire settings with larger center stones are on the rise. "Before lab-grown diamonds existed, the standard size for the center stone on an engagement ring was 1 carat. Today, with lab-grown diamonds, it's closer to 2 carats each," says Sherman.

Insure your purchase. Lab-grown diamond jewelry can also be insured, just like jewelry made from natural stones. "We strongly suggest insuring items of value you'll use day to day, just like insuring your car. To that end IGI provides affordable independent appraisals for finished jewelry, as well as loose gemstones, welcomed by the world's most highly regarded insurance providers," Levy says.

Ignore the critics. Naysayers will cite anything from the possibility that lab-grown stones could lose their value (only time will tell) to environmental impact (unless you opt for a vintage or antique ring, no choice will be carbon neutral). Like nearly every element leading up to your big day, you want your engagement ring to be a reflection not only of your taste but your values. If you've done your research and found a lab-grown ring that meets your aesthetic requirements, your budget, and that you'll feel confident wearing for the rest of your married life, then by all means, go for it.
