For your consideration is a beautiful smokey topaz ring which is prong set on a filigree band.  It is marked 925 Sterling Silver and signed CNA Thailand.  It is a vintage piece.  I have not cleaned it, leaving that up to the new owner.  It is a size 6.75.  

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.
