Overview
This striking mid-century brooch features a large, luminous, diamond-shaped green chrysoprase cabochon. The stone is secured in a delicate, beaded sterling silver bezel frame that exemplifies the clean, geometric lines of late Art Deco and early Retro-era European design.
Story
In the 1930s, German designers revolutionized jewelry by pairing bold, semi-precious stones like chrysoprase with sterling silver. This vibrant green gem was once a favorite of Frederick the Great, who used it to decorate his palace.
Maker / Origin
While the specific workshop is unidentified without a visible maker's mark, this piece strongly reflects the output of the historic jewelry hub of Pforzheim, Germany. Known as the 'Goldstadt' (Golden City), Pforzheim was world-renowned for combining industrial precision with artistic hand-finishing, producing high-quality silver jewelry exported across the globe.
Condition & Value
The chrysoprase appears to be in excellent condition with a smooth, scratch-free surface and no visible chips. The sterling silver bezel shows a light, attractive patina that highlights the beaded detail. Excellent condition preserves the maximum value for collectors.
