Graphic Grace – Vintage Art Deco Diamond and Onyx Bracelet, Circa 1920

An unmistakably Deco piece from the 1920s, this platinum bracelet brings together bold geometry and quiet craftsmanship. Its central trio of old-cut diamonds (approx. 2.90ct total) is framed by polished onyx and over a hundred rose-cut diamonds, arranged with confident symmetry. The fine engraving along both sides is a subtle nod to the masterful hands behind every detail, from the design sketch to the goldsmithing, setting, and finish. On the wrist, it feels sculptural yet refined: modern in line, timeless in spirit.
