Beautiful Jay King, signed necklace/pendant set!  The pendant is removable and could also be worn on a chain, according to taste.  Necklace measures 18” but does extend to 21” with its sterling extender.  Pendant measures 2 3/4” in overall length including the bale.  It is about 1 1/2” at its widest point.  Comes with romance card/wipe cloth, as shown in pictures.  Very versatile.
