Gold Solitaire Ring with Green Gemstone

This item is a slender solitaire ring crafted from yellow gold, featuring a vibrant green gemstone focal point. The band is a traditional thin shank that tapers slightly as it approaches the head of the ring. Within the interior of the shank, multiple hallmark stamps are visible, including a '10K' mark indicating the gold purity and an additional maker's mark or symbol, possibly an 'S' or stylized logo, suggesting a mid-to-late 20th-century manufacture. The gemstone is held in a multi-prong basket setting, or 'v-tip' style typically associated with fancy cuts like a marquise, heart, or pear shape, though only the corner is visible here. The color of the stone is a bright, yellowish-green, consistent with peridot or a synthetic variety. The gold exhibits a high-polish finish with minor surface abrasions and superficial scratches consistent with regular wear. There appears to be some minor patina or dirt accumulation near the setting and within the stamped recessed areas. The overall construction is dainty and lightweight, characteristic of everyday fine jewelry rather than a substantial heavy-cast piece.
