Emerald Cut Blue Stone Appraisal

Vintage 10K Gold Ring with Emerald-Cut Blue Stone

This item is a vintage ring, likely crafted from 10 karat gold based on the provided context '10K', featuring a prominent, large, emerald-cut blue stone as its centerpiece. The stone exhibits a vibrant, deep blue hue and displays excellent clarity with visible facets, contributing to its brilliance. It is set in a four-prong setting, with the prongs appearing to be integrated into the surrounding gold work. The gold setting features an ornate, possibly filigree or repoussé, design on the shoulders leading up to the central stone. This elaborate detailing is visible on both sides of the stone and suggests a period style, potentially Art Nouveau or Art Deco revival, or mid-20th century. The gold appears to be yellow gold, showing some natural tarnishing or patina consistent with its age, which further supports its vintage classification. No significant damage like chips or cracks are visible on the blue stone from the provided images, though a closer inspection would be required to confirm its perfect condition. The band itself is not fully visible but appears sturdy. The overall craftsmanship suggests a well-made piece of jewelry, with attention to detail in the gold work. The large size and striking color of the central stone make this a statement piece. Without a closer view of the hallmarks or maker’s marks, a precise age is difficult to determine, but the style points to sometime between the 1920s and 1960s. The blue stone could be a synthetic sapphire, blue topaz, or even a glass imitation, given the setting style and potential vintage market for such pieces.
