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.

Love Kimaï! The designs always stand out, and the prices are quite affordable when you realize these pieces are forever. Amazing quality and customer service! 

Bought the Ivy necklace as a gift. It’s beautiful and delicate, and I love the ethical mission behind the brand. User-friendly website and speedy delivery too.

Earrings are best value for money, necklace a little over priced for what they are

I have ordered many items (earrings, bracelets, necklaces) and receive so many compliments, great quality 

Stunning design and sustainable DNA. What's not to love

Love the brand and its mission! I've heard from lab-grown diamonds for the first time thanks to their brand awareness. I love everything about Kimai, the design is beautiful and the quality is great. I have been recommending it to all my friends and family, spreading the word about the innovative sustainable lab-grown diamonds! 

The jewelery  is so pretty and love that it’s sustainable.
