These 1920's Art Deco drop earrings are made of hand-cut natural crystal quartz (rock crystal) beads and sterling silver chain and screw-on tops.
Each earring measures 2 5/16" long and the widest beads in the bottom segment are a little over 1/2" wide from corner-to-corner facet. Each of these beads on the lower two segments has flat tops and bottoms with sharp facets on the sides of the disks. I have tested the beads and they are genuine quartz crystal, not glass, and they are clear and free of inclusions.
The top beads are faceted rounds with sterling ball-end pins securing them to the cup backs. The screw-back findings are marked "Sterling" on the ends with some hand-engraved letters. Condition is very fine with no damage.
