THis is a Very Pretty Silver Pendant from Mexico with a Black Cabochon Bezel Set stone that I believe is Onyx.
It hangs down 1 1/2" including the Large Bale that can accomodate many sizes and styles of a chain(not included) to make a Lovely Necklace. It is 1" across. It is marked on top of bale, MEX GC80 925 and is in Very Good Condition.
