Vintage Silver Signet Ring with Green Stone Inlay

This item is a vintage signet ring, likely crafted from sterling silver, given its common use in such designs and the typical patina observed. The ring features a rectangular-shaped, bezel-set green stone, possibly jade, onyx, or another semi-precious gemstone, serving as the central focal point. The stone exhibits a dark, opaque green hue with no visible inclusions or translucency from the provided image. The ring itself appears to be a thick, robust band with a raised, flattened rectangular face where the stone is set. Distinguishing elements are decorative engravings or embossed details on the shoulders of the band, flanking the central stone. These appear to be abstract or possibly stylized animal figures, though specific details are difficult to discern from the image. The craftsmanship suggests a hand-finished or semi-mass-produced piece from a bygone era, potentially mid-20th century, consistent with a 'grandmother's ring' provenance. The silver displays a soft, aged patina characteristic of older silver jewelry, indicating some wear from regular use. There are no obvious signs of major damage such as cracks, chips, or significant dents, suggesting it has been reasonably cared for. Manufacturing marks are not visible in the provided images, which would typically be located on the inside of the band. The overall condition is good, showing appropriate wear for its presumed age, adding to its character without detracting significantly from its appeal. The design is classic for a signet-style ring, offering a timeless aesthetic.
