Articulated Green Hardstone Pendant in Silver-Toned Mounting

This item is an unusual articulated pendant featuring two polished cabochons of a deep green hardstone, likely nephrite jade or aventurine quartz, characterized by a smooth, waxy luster and internal mossy inclusions. The piece is constructed in two distinct sections: an upper domed cap and a larger oblong lower body. These stone components are housed within a silver-toned metal mounting, possibly sterling silver or a white metal alloy. The metalwork features a distinctive 'beaded' or granulated texture along the edges where the metal grips the stone. A horizontal metal band separates the two sections, suggesting a hinged or articulated movement mechanism typical of late 20th-century artisan jewelry. The top of the piece is finished with a simple wire bale for suspension. Regarding condition, the metal shows a significant dark patina and surface oxidation, particularly in the recessed areas between the beads, which is consistent with age and exposure. There are minor surface scratches on the stones visible under light, but no major chips or fractures are apparent. The craftsmanship appears to be hand-wrought rather than mass-produced, indicated by the irregular spacing of the decorative beads. No hallmarks or maker's marks are visible in the provided image, but the style is reminiscent of mid-to-late 20th-century brutalist or organic-style studio jewelry.
