10K Gold Signet Ring with Green Stone

This item is a 10K gold signet ring featuring a rectangular, possibly square-cut, dark green gemstone or inlay. The ring is crafted from yellow gold, exhibiting a polished finish with some visible surface scratches and minor wear consistent with regular use. The band appears to be of moderate thickness, tapering slightly towards the palm side. The central feature is the dark green element, which could be an emerald, tourmaline, or a synthetic stone, set flush within a bezel or similar smooth setting that frames its perimeter. The color of the stone is a deep, rich green, appearing opaque or semi-translucent. A prominent '10K' mark is clearly visible on the interior of the band, indicating the gold purity. The overall design suggests a contemporary or mid-20th-century aesthetic, leaning towards a simpler, more classic style often associated with men's jewelry. There are no other discernible maker's marks or engravings visible from the provided images. The craftsmanship appears solid, with no immediate signs of damage or repair to the setting or stone, although closer inspection would be required to verify the integrity of the stone's surface and edges. The ring's condition is good, showing patination and superficial wear but no significant defects that would hinder its function or aesthetic appeal.
