Kimaï

Kimai is a direct-to-consumer fine jewelry brand founded in November 2018 by Sidney Neuhaus and Jessica Warch, headquartered in London with a retail presence in Paris. The brand crafts engagement rings, wedding bands, earrings, bracelets, and necklaces exclusively from lab-grown diamonds and recycled 18k gold, positioning itself around a 'made, not mined' philosophy of traceability and lower environmental impact than traditional mined-diamond jewelry. Kimai has been worn publicly by celebrities including Meghan Markle, Reese Witherspoon, and Emma Watson, and operates stores in London and Paris alongside its e-commerce site.
