Vintage Necklace with Red and Black Beads

This is a necklace that I can't stop looking at; there are several different types of beads and each is beautiful. There are round black beads separated by detailed metal separator bead, then red clear faceted separator. In the center we see large red and black bead and larger metal ornate beads, separated by solid red beads. In the center is a large oval black bead. The necklace measures 26" and has a gold tone toggle clasp.
