This is a unique handmade pendant comprised multiple pieces of different-colored green art glass fused to a black art glass background.  It was made with multiple kiln firings to create the individual variegated pieces which were then fused to the background piece.  This unusual necklace is 1.75 inches long by 1 inch wide.  It has a silver bail and is strung on an 18 inch long, 4-strand bright green satin necklace with a lobster clasp.
