For your consideration is a vintage pendant.  I believe this to be a blue green and black agate.  It is mostly a blue color.  It is in a teardrop shape and bezel set in a gold tone metal.  It is 1 1/8" tall and a total of 1 1/2" long with the slide.  A beautiful piece of nature.

I have recently acquired a very large estate.  There were many jewelry and collectible pieces.  I will be listing many more items in the next several months as I dig thru all the pieces.  Thanks for looking.  Check my other listings for more jewelry, vintage, antiques, collectibles, clothing, fabrics and holiday items.
