Crystals were all the rage in the late 20’s and early 30’s. They never do seem to go out of fashion. The Purple ones in this piece are Czech glass and were rescued from a vintage necklace. They were then paired with white potato pearls and sterling.  

The length of the necklace is 16in. You can double it up and wear it as a bracelet (tightness may vary depending on your wrist size) The clasp is a sterling toggle clasp.
