Unsigned 1940s Harry Iskin Attributed Floral Brooch Blue-Green Art Glass Cab

Exquisite unsigned Harry Iskin–attributed brooch circa 1940s. This sculptural floral design features Iskin’s signature die-struck scrollwork & layered petals, set with a luminous blue-green domed art-glass cabochon in an open-back prong mount. The metal shows a warm aged patina & retains a rollover clasp typical of Iskin’s mid-century construction.
While unmarked, the craftsmanship, form & proportions closely mirror his signed pieces from the same period (& he didn’t sign all his work). Possibly a department-store release or early studio variant.
Excellent vintage condition with age-appropriate wear; faint adhesive under stone may indicate a later replacement.
Measurements: approx. 3″ across.
A stunning & highly collectible example of American Retro-Modern design attributed to one of the era’s most elegant jewelry houses.
