Deltah Crystal Bead Necklace

This lovely necklace probably dates from the 1930's. It is constructed of clear glass beads alternating with smaller beads and separated by gold filled spacer beads. The beads are strung on a gold filled chain and the closure is also gold filled. In the original box marked Deltah. A similar set is shown on p. 139 of Ettinger's Popular Jewelry 1840-1940.
