A striking 14K yellow gold necklace from the 1940s Retro era, featuring a bold design with sculptural curves and gemstone accents. The centerpiece showcases a fan-shaped motif adorned with 1 marquise-cut diamond (approx. 0.015 carats) and 63 round and old mine-cut diamonds totaling approximately 0.28 carats. Accentuating the top of the design are richly saturated rubies totaling approximately 5.50 carats, arranged in concentric arcs. The necklace is crafted with a coiled gold tubogas-style collar, typical of the glamour and bold geometry of the Retro period.
