Lab-grown Diamonds Gain Popularity Despite Sustainability Concerns

As sales of lab-grown diamonds surge, questions about their environmental impact and sustainability practices come to the forefront.

Lab-grown diamond sales in the U.S. increased by 16% in 2023, with many buyers attracted by lower prices and ethical considerations.
Despite claims of sustainability, the production of lab-grown diamonds requires significant energy, and many manufacturers lack transparency about their operations.
Some lab-grown diamonds are produced using renewable energy or offset by carbon credits, but these practices are not widespread.
The majority of lab-grown diamonds come from India and China, where a significant portion of electricity is generated from coal.
The debate over the value and sustainability of lab-grown versus natural diamonds intensifies as the market for lab-grown diamonds grows.
