This is an awesome piece - measures 2.25" across. That huge center stone is a cut crystal not a lucite stone. There are 4 amber bakelite tear drops - Semi-chrome tested them myself. This one has an antique gold filigree coloring. Secure clasp - signed on the backside. It's very 3 dimensional measuring just over 1" tall. this company was established in 1920 and continued to produce beautiful jewelry and ceased production in 1990 - pretty long career. My best guess is 1930-40. Lovely piece.
