## About Aether Diamonds

Aether Diamonds is a climate technology startup founded in 2018 and headquartered in New York City.

The company is recognized as the world's first manufacturer of carbon-negative diamonds, created entirely from atmospheric carbon dioxide. Aether Diamonds aims to redefine the diamond industry by transforming air pollution into high-quality, ethical jewelry, providing an alternative to conflict diamonds and fossil-fuel-based synthetics. The company specializes in sustainable fine jewelry, including customizable engagement rings, wedding bands, and other bespoke pieces made from its unique lab-grown diamonds. Aether's production process involves capturing CO2, converting it into methane, and synthesizing diamonds using advanced technology. Each carat produced removes 20 metric tons of CO2 from the atmosphere, highlighting Aether's commitment to environmental stewardship. As a certified B Corporation, Aether Diamonds emphasizes social and environmental performance, appealing to eco-conscious consumers and luxury buyers who value sustainability.
