Gemstone chip & silver tone flower etched beads necklace jewelry

Necklace is in good condition and kept in a clean smoke free home. Gemstone chips are white with a small amount of light blue. I do not know what the gemstone is. Not sure what the beads are thread on because beads are tight together. —Silver tone screw back clasp, thin silver tone beads towards top meet 1 larger silver tone bead then the round silver tone beads with a flower etched on each side alternate with the gemstone chips. Silver tone beads graduate with largest front and center. It’s a beautiful piece-does have tarnish. 17” #vintage #jewelry #gemstone
