Antique Victorian Gold Filled Agate Cameo Pendant with Hook Necklace

c1890 Slightly rose gold filled Victorian necklace featuring an agate carved from banded agate with lady in profile, on the back is a hook you can add pocket watch/charm or pocket watch. The chain is an interesting link and 3/16" wide, finished with a barel clasp. 18" length chain. The pendant is 1" in length. I've priced the piece down due to some greening on links on the chain, the cameo also could you using some cleaning but overall an interesting and wearable piece of antique jewlery.
