For your consideration is a vintage Kenneth Lane necklace.  This is a faceted black glass beaded necklace with rhinestone rondelles.  The necklace is 40" long, so you can have a flapper type necklace, or double it and have the two strand look. 

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.
