Sherman faceted black glass bead earrings clusters clip back vintage ll2857

Signed Sherman, these earrings are clusters of faceted black glass beads that look like black jet. They consist of 7 beads per earring and have clip backs signed Sherman. The backs and attachments are silver tone. The earrings are just a hair under 1 inch and 5/8 inch wide. Condition is perfect on the front and with considerable finish wear to the metal clips. You can still see the signature however and the clips are as strong as new. Other sellers describe the beads as Swarovski. Can't swear to that.
