A wide vintage Retro 18k rose gold tank bracelet with French hallmarks, circa 1940. This bracelet is a classic example of a Retro tank bracelet, named after the tread of a tank. World War II greatly influenced jewelry design and styles, as women started to join the work force and choose jewelry that was more bold and durable than Art Deco styles from 10 years before. The alloy of copper is added to gold to create this rose hue. This bracelet has French gold marks on the tongue and has a pretty and dimensional design. The bracelet is 0.75 inches wide, and about a 7 inch interior circumference.
