This brooch was made by a master craftsman. Look at the detailing on the balance scale, and especially the ribbon that winds through the middle of the brooch. 2" by 2", with a sturdy safety clasp. Marked Sterling by Cini with a copyright symbol. According to Rezazadeh, "...the jewelry is considered among the best manufactured jewelry in America." The company ceased production in 1970, but some production was made in the 1990s. This piece is from the earlier period. Excellent vintage condition.
