Arthur King & Ilias Lalaounis (ARK & LJ) 18K Gold Fire Opal & Diamond Ring, 1960

About the Item

A rare and sculptural 18K gold ring stamped ARK & LJ, produced during the short-lived collaboration between Arthur King and Ilias Lalaounis, two of the most influential jewelry designers of the mid-20th century. The ring centers a vivid faceted fire opal weighing approximately 8.5 carats, displaying a rich orange-red hue and exceptional internal glow. Surrounding the opal are bezel-set diamonds totaling approximately 0.68 carats, integrated into an openwork gold framework that reflects Arthur King’s bold modernist design language, refined by the precise goldsmithing associated with Lalaounis. Architectural in form and elevated in profile, the ring exemplifies studio jewelry of the period, combining expressive sculptural design with fine materials and meticulous craftsmanship.
