Aether Diamonds
Aether Diamonds is a Specialty Polymers, Coatings & Surfaces company founded in 2018 and based in New York, USA. It has raised $21M in total funding, most recently a Series A in 2022.
Founded in 2018 and based in New York, Aether Diamonds (legal entity Impossible Diamond, Inc.) produces what it markets as the world's first carbon-negative diamonds, synthesizing captured atmospheric CO2 into the hydrocarbon feedstock used to grow diamonds rather than relying on petroleum-derived material. The company says each carat purchased corresponds to net removal of CO2 from the atmosphere. Aether raised $18M in a 2022 Series A led by Helena and Trirec, bringing total funding to about $21M, with backers including Sound Ventures and Khosla Ventures.
Reframes lab-grown diamonds as a carbon-removal product, using captured CO2 as the raw material for a high-value crystal.
