Patented in Japan

  • Developed through years of observing differences in wrist anatomy, proportion and movement, the method allows each bangle to be shaped around the individual rather than a standard oval. The exterior remains quiet and sculptural while the inner curve is refined in precise increments for the wearer.

    Patented in Japan under Patent No. 7703264. Patent applications are pending in key European jurisdictions.

How the Method Works

The patented method concerns the design of a bangle’s inner curve. It translates the observations made during a Wrist Assessment into a curve, opening and inside circumference refined for the individual wearer.

  • Observe the Wrist

  • Natural contours and movement
    Patented in Japan

  • A Wrist Assessment considers the contours, thickness and movement of the wrist. These observations provide the starting point for the bangle’s individual proportions.

  • Shape the Inner Curve

  • Secure, considered movement
    Japanese Patent No. 7703264

  • The value of the method is felt in daily wear: a bangle that relates more thoughtfully to the wearer’s contours and preferred balance. Each piece remains a work of jewellery, individually crafted in Japan—not a medical device or a promise of a universal fit.
