This was purchased circa 2005 at a Cape Cod flea market, from someone who sold international goods.  IT IS SOOOOOO BEAUTIFUL!  Different green hues in the tiny beads, medium beads, and larger painted beads.  It has good weight to it.  It is a necklace, and can be knotted/looped down the middle or around the neck in various ways (even scarf-like).  This has other uses -- can be a belt!  An unusual necklace!
