An exceptional vintage 583 gold (approximately 14K) convertible brooch/pendant, featuring a large faceted Kunzite surrounded by sparkling rose-cut diamonds. The ornate openwork setting is richly embellished with scrolling foliate motifs, applied beadwork and additional rose-cut diamonds, creating a beautifully dimensional design.

The piece bears a 583 fineness mark with a profile-and-hammer style assay symbol, appearing consistent with an early Soviet worker-and-hammer hallmark, circa 1927-1955. A distinctive and highly collectible jewel combining kunzite, antique-cut diamonds and elaborate gold craftsmanship.
