This is a VINTAGE KATE SPADE NECKLACE.  It is GOLDTONE and has GREEN STONES.  I do not know what the stones are made of.  They have shades of green and aqua.   If laid out flat, it measures appx. 19 1/2" long.  It comes with a small fabric carrying bag marked Kate Spade, New York.   The necklace is  NEW with it's TAG.  Excellent condition.    It is a striking necklace!   Shipping is $6.00 if within the USA.   Check out my other items.  I have lots of vintage jewelry listed, and am always adding more.    Please add me to your favorites list.
