Oval medallion brooch

Oval medallion brooch, 18k gold frame setting a cameo on diaphanous agate about Hebe feeding the eagle of Jupiter, a mythological metaphor of eternal youth. Remarkable high-end carving, great finesse of execution. The frame adorned with an applique frieze, included a decorative element at the bottom (pearls ...), here absent. French work XIXème from the Napoleon III period (minor chip at the bottom of the cameo). In its case. 14.36 g. Dimensions 60 x 45 mm. Superb!
