This delicate piece is superb. The small cameo is hardstone as so many of the older cameo carvings were. Bookchains go back a long way and are very sought after. All original, this chain fastens from front ( not back) as was customary at this time. The three dangle pieces of front sets this one apart from similar ones which I have sought over the years. All original and in flawless condition, this piece is outstanding.
