B.S.K brooch beautiful large vintage piece

This is a beautiful large vintage B.S.K. brooch. Has a brown stone in the middle of a gold like! Nice touch for any scarf or shirt! There is very little information about the designer or design mark B.S.K online or in research books. The company was founded in New York in 1948 and was in business until the mid 1980s. The letters BSK stand for the first initials of the three owners: Benny Steinberg, Slovitt and Kaslo.
