That diamond ring your newly engaged friend is showing off? It may not be a traditional diamond.
More than a third of all engagement rings with center stones purchased last year were created in a lab, according to an online survey of nearly 12,000 U.S. couples by wedding-planning website The Knot. That’s double the number from 2020.
A natural diamond takes billions of years to form deep within the earth. The diamond industry, it seems, evolves almost as slowly. But a major shift seems to be under way.
As the technology to make lab-grown diamonds has improved, production has increased and retail prices are falling. Their growing popularity, especially among younger consumers, has caught the attention of jewelers and watchmakers — and is challenging traditional diamonds that are mined from the earth.
It’s not just engagement rings. Diamonds grown in a lab accounted for 13.6% of the $88.6 billion in diamond jewelry sold globally in 2022, up from less than 1% in 2015 where they had hovered since the early 2000s, according to Paul Zimnisky, a diamond industry analyst.
