Modernist Sterling Silver and Baltic Amber Pin. The center square contains a larger round cabochon of real Baltic Amber. The two side squares contain Pyramid shaped amber that stands out much further than the surface of the silver. The piece measures 2" long and 7/8" tall. The large center square is 3/4" and the round amber piece is 5/8". The smaller squares are 1/2" and the Pyramid shaped amber is 7/16" and just a hair under 1/4" tall. The back is marked 925. There is a makers mark but it is hard to read.
Excellent vintage condition. Light signs of wear from polishing and use.
