SORRENTO is a US brand used in costume jewelry, which was usually made of gold-filled metal. 1/20 12K GF means that 1/20 of the total weight is 12 karat gold. GF – Gold Filled , not just a thin coating (like “gold plated”), i.e. higher quality decorative jewelry , often made in the 1950s-1970s. This particular brooch is very likely from the 1960s-1970s , considering the filigree work elements , green jade decorated stones and a characteristic vegetal, naturalistic design (popular in the post-war years and the late modernist period).
