Diamond Tie Tack Appraisal

Single Bezel-Set Diamond Bar Pin/Tie Tack

This item is a single bar pin or tie tack featuring a central, round brilliant-cut diamond set within a warm-toned yellow gold bezel. The diamond appears to be a 'circle cut,' which is another term for a round brilliant cut, consistent with the 1970s style indicated in the context. The bezel setting fully encircles the diamond, providing a secure mount and a smooth, continuous surface that enhances the stone's brilliance and offers significant protection against chipping. The gold setting exhibits a polished finish, reflecting light clearly without noticeable scratches or dings, suggesting good overall condition for its age. Attached to the bezel setting is a slender, curved gold wire, which forms the functional pin component, designed to pass through fabric and secure the item. The wire appears to be solid and retains its original shape, showing no signs of bending or damage. The overall aesthetic is one of understated elegance, typical of jewelry from the 1970s which often featured minimalist designs allowing the quality of the materials to speak for themselves. There are no visible maker's marks or stamps in the provided images, which would require closer inspection. The diamond itself exhibits good clarity and brilliance, though specific carat weight and color grade cannot be determined without professional assessment. The craftsmanship appears to be of good quality, with a well-executed bezel setting that is flush and even around the diamond.
