Avon Jade Green Baroness Celtic Cross Pendant

Vintage necklace from Avon catalog 1973. Faux Jade stone in a gold colored open-work cross. This was from the Baroness collection where the earrings and fashion ring were also made to coordinate with this. I'm not sure if this is the original chain, but it looks like the clasp is a very old style. Chain is goldtone 16" + 3" extender chain.
