Vintage ivory resin chains (love their faceted finish) in three strands offset a vintage goldtone compact pendant by Germaine Monteil--its rocky road finish complimented by vintage brass beads and clasp at back.  Approximately 18" long, compact is 2.75" by 2.25".  

Note:  If you're at all superstitious, you may want to pass on this one...the mirror has a crack across its surface!  (We're willing to take our chances with a necklace this fun, though...)
