New vintage TRI-GOLD metal cuff bracelet

New vintage TRI-GOLD metal cuff bracelet Tri-gold (now broadly called Mixed Metals) trend was very strong in the 1970s-1980s. Featuring “3 gold” colours: white gold + yellow gold + rose gold colours. It was a new modern trend that appealed to a lot of people. It was fashionable, luxurious, minimalist, modern. Similar to today’s mixed metals trend, tri-gold is not just aesthetically beautiful, but easy to wear and match with any outfit! UNIQUE DETAILED FABRICATION! Made in Japan. 2x10 mm individual slices of metal pieced together. New vintage c. 1970s. Hallmark: JAPAN. I don’t see any other hallmarks regarding gold content so I’m assuming it is a high quality Costume metal. Overall bracelet: 3X6 MM??? Need to remeasure, 9 mm wide, 1mm thick
