This is a beautiful pendant.  It is a green version of a cat's eye stone.  It has the iridescent stripe longways that moves side to side when you look at it in a bright light.  It is on a silverplated plate with the necklace loop and wrapped in a silverplated chain.  No necklace included, this is only the pendant.  It is 3/4 inches wide and 1 1/4 inches tall. It is 1/4 inch thick.  A beautiful piece to add to any formal or informal occassion. It only weighs about 2 oz.   There is a little tarnish on the pendant.  See photos for full description.
