Victorian Pink Agate Necklace

I acquired this beautiful genuine Victorian necklace from an estate of Victorian jewelry that was absolutely incredible! I sold quite a bit of it to a private collector, but kept a few pieces for myself.  

This lovely vintage necklace has a large center agate that measures 1 by 1 and 1/2 inches and the necklace itself is 24" long, not including the 2 and 7/8" drop in the center. I believe that these are pink lace agates.
