This vintage piece may be part of a Trifari earring or necklace set, featuring gold-tone floral and tassel designs. This piece bears distinct design and historical characteristics of mid-20th century American costume jewelry, likely from the 1950s or 1960s. The Golden Age of Costume Jewelry (1950s–1960s): In the post-World War II period, designer jewelry made not of pure gold but of plated alloys surged in popularity. Women sought jewelry with a dramatic, rich presence that would fit the elegant "New Look" fashion without paying the prices of precious metals.
