Company Background
Kimai was born from a desire to modernize the jewelry industry. Founders Jessica Warch and Sidney Neuhaus both grew up in Antwerp families tied to the diamond trade. Disillusioned with the lack of transparency in traditional jewelry, they launched Kimai in 2018 to offer a cleaner alternative. The duo chose lab-grown diamonds—identical to mined stones but free from conflict and environmental harm. They also committed to using only 18k recycled gold, avoiding the waste of mining. With direct sourcing and no middlemen, Kimai built a fully traceable, ethical supply chain. All their pieces are handmade in Antwerp by expert craftsmen. The brand quickly gained attention from global press and celebrity supporters, including Meghan Markle. Today, Kimai stands for more than just beautiful jewelry—it represents conscious luxury. With design rooted in innovation and ethics, the company has become a leader in the sustainable fine jewelry space.
Product Range
Kimai carries a wide range of exquisite jewelry, from earrings, necklaces, rings, and bracelets to engagement rings. Their designs of jewelry are both modern and timeless, perfect for everyday use or a special occasion. They also have self-gifting options, wedding sets, and men’s collections. The products are mostly customizable for most customers and even work together with their team on bespoke designs. Kimai also occasionally refreshes their catalog with limited-edition designs and seasonal additions, keeping the catalog updated and trendy for conscientious consumers.
Metals Used
All Kimai pieces are crafted using 18k recycled gold. They offer yellow, white, and rose gold to suit diverse tastes. Recycled gold reduces damage to the environment and avoids the negative impacts of traditional mining. Kimai uses no plating or fillers but genuine, strong metal. Kimai aims to give long-lasting jewelry that retains its value and good appearance for years. Each piece is hand-polished by expert craftsmen in Antwerp.
Stones Used
Kimai only uses lab-created diamonds. They are chemically and optically identical to earth-mined diamonds but cultivated under controlled conditions. They’re greener, ethical, and conflict-free. All diamonds are graded by IGI or GIA-graded grading labs. Diamonds are from tiny pavé settings to larger solitaires up to 2 carats. Kimai cuts each diamond for brilliance in mind, adding sparkle and sophistication with no compromise. Sourcing guarantees complete traceability from lab to jewelry box.
