Rooted In Rarity
About Yūsei & Co
Founded on a legacy that began in 1992, Yūsei & Co. is a jewelry house built on a deep-rooted passion for rare and extraordinary treasures. It all started with a private collection of diamonds and gemstones, curated by a woman with an eye for nature’s most beautiful rarities. Her fascination with Earth’s hidden wonders laid the foundation for what would become a generational pursuit.
The next chapter brought a new vision—expanding the collection to include meteorites and unique minerals from around the world. This evolving passion led to showcasing pieces at renowned auction houses like Sotheby’s, and ultimately, to the birth of a brand dedicated to the extraordinary. The name “Yūsei,” meaning wandering star in Japanese, reflects the brand’s soul: a journey across the earth and beyond, in search of timeless beauty and cosmic inspiration. Yūsei & Co. is where celestial influence meets earthly elegance.
Every piece in the Yūsei collection is either discovered or designed with intention. Traditional designs are set aside in favor of the remarkable gems and jewelry that captivate at first glance. Inspired by the stars, nature, and Japanese craftsmanship, each creation tells a story of wonder, rarity, and refined artistry. With materials sourced from the gem-rich landscapes of Thailand, Colombia, and Brazil, Yūsei & Co. offers more than adornment—it provides the chance to own a piece of time, nature, and the universe itself.
