Vintage Camphor Glass Pendant Center Pearl With Chain 1934 Provenance Silvertone

Star design in the glass with center pearl on a rectangular piece of frosted reversed etched camphor glass. Attached note reads "Bethlehem Star from my Grandma in 1934" establishing the piece to be at least 91 years old. I don't think the 16" chain with spring ring clasp is that old. Metal is silver tone in color. Estate find. Unmarked and untested.
