Founded in 2011 by Japanese designer Mio Harutaka, the eponymous fine jewelry maison creates enchanting one-of-a-kind pieces inspired by the beauty of nature and the poetry of everyday life. Drawing on her Japanese heritage and a lifelong fascination with animals, flowers and organic forms, Mio transforms precious gemstones into delicate, sculptural creations that evoke a sense of wonder and timeless elegance. 

Each jewel reflects a harmonious balance between exceptional craftsmanship and artistic imagination. Combining rare diamonds and coloured gemstones with playful yet refined motifs—from birds and butterflies to botanical forms—the maison celebrates individuality through creations that are both whimsical and sophisticated. Designed to become enduring treasures, every piece is crafted with meticulous attention to detail and intended to be cherished for generations. 

Beyond aesthetics, Mio Harutaka is deeply committed to responsible sourcing and ethical practices. Working closely with the non-profit organization Diamonds for Peace, the maison supports initiatives that improve the lives of mining communities while promoting greater transparency throughout the diamond supply chain. This commitment reflects a broader philosophy: creating jewelry that is not only beautiful, but meaningful—for those who wear it and for the people who help bring it to life.
