Art Deco Camphor Glass Diamond Sunburst Filigree Ring

This exquisite Art Deco period ring is crafted in 14k white gold, showcasing a classic 'Camphor Glass' design popular in the 1920s and 1930s. The focal point is a sizeable oval-shaped piece of frosted camphor glass, featuring a characteristic 'sunburst' or 'starburst' radial pattern carved into the reverse side, which creates a translucent, glowing effect. At the direct center of the glass is a lozenge-shaped white gold setting head containing a single round-brilliant natural diamond, estimated at approximately 0.03 to 0.05 carats. The mounting features intricate openwork filigree on the gallery and shoulders, characterized by delicate lace-like patterns and geometric mille-grain detailing along the oval bezel. The craftsmanship indicates high-quality die-struck production common to the era. The white gold retains a bright, cool luster with minor surface abrasions consistent with gentle wear over a century. The camphor glass appears intact with no visible internal fractures or heavy scratching, and the delicate filigree remains structurally sound with no broken wires. This piece is a quintessential example of early 20th-century costume-fine hybrid jewelry, merging technical gold work with the then-fashionable frosted glass aesthetic.
