For your consideration is a vintage Judith Jack Sterling Silver 925 earrings.  These have a large crystal center with Marcasites around the outside.  They are 3/4" square.  

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.
