Vintage Diamond Geometric Two-Tone Band Ring

This item is a vintage-style decorative band ring featuring a distinctive geometric pattern. The construction appears to be two-tone, likely consisting of a yellow gold base with white gold or platinum accents on the face. The design showcases a repeating series of triangular and diamond-shaped chevron motifs, within which small round brilliant-cut or single-cut diamonds are grain-set. The scalloped edges of the band provide a refined silhouette. The metal displays a warm patina consistent with age and regular wear, showing minor surface scratches and softening of the detailed engraving. The stones appear securely set, though some minor buildup of dust and skin oils is visible behind the settings, which would benefit from professional ultrasonic cleaning. The overall craftsmanship suggests a mid-20th-century aesthetic, possibly Art Deco revival or late vintage era. The piece is presented in a cream-colored velvet-lined jewelry box, though a retail tag attachment suggests it may be part of an estate sale inventory. No specific hallmark is visible in the current view, but the design quality indicates a professional jeweler's work.
