Kimai creates luxury, sustainable jewelry from 18k recycled gold and lab-grown diamonds, and offers full transparency.

Founded in 2018 by best friends Jessica Warch and Sidney Nehaus who wanted to bring a new level of transparency to the jewelry industry. Our pieces are crafted exclusively from 18k recycled gold and lab-grown diamonds. Kimaï was the first lab-grown diamond brand to be stocked on Net-a-Porter in 2021, and named by Fast Company as one of the most innovative companies in the world. Diane Von Furstenberg is an investor in the business and customers include Meghan Markle, Emma Watson, Jessica Alba and Eva Chen. 
High-quality, low-impact, and fully traceable – it’s that simple.
