Vintage 1974 Modernist style silver pendant w/green gemstone by Joy.   Marked on the back JOY '74.  Measures 1 7/8" x 2 1/8".   In good condition - may need a good cleaning.  I do not clean vintage pieces I leave the original patina on it, so it might need a good cleaning.   I have other collectibles in my eBay store and feel free to take a look.  Once again thanks for taking a look.
