BEHIND THEIAN
THEIAN takes its name from Theia, the Greek goddess of sight. She symbolizes vision, clarity, and radiance—the very essence of our creations.
Our story began in diamonds. Years in the industry gave us access to the rarest stones—and inspired us to merge that heritage with our love of sunglasses to create something truly unique.
