The muted sounds of hammering and sanding drift down to the first floor of Bario Neal, a jewelry store in Philadelphia, where rustic artwork that mimics nature hangs on warmly-lit walls.
Waiting for one of those rings is Haley Farlow, a 28-year-old second grade teacher who has been designing her three-stone engagement ring with her boyfriend. They care about price and also don’t want jewelry that takes a toll on the Earth, or exploits people in mining. So they’re planning on buying diamonds grown in a laboratory.
“Most of my friends all have lab-grown. And I think it just fits our lifestyle and, you know, the economy and what we’re living through,” said Farlow.
In the U.S., lab-grown diamond sales jumped 16% in 2023 from 2022, according to Edahn Golan, an industry analyst. They cost a fraction of the stones formed naturally underground.
Social media posts show millennials and Generation Zs proudly explaining the purchase of their lab-grown diamonds for sustainability and ethical reasons. But how sustainable they are is questionable, since making a diamond requires an enormous amount of energy and many major manufacturers are not transparent about their operations.
