Antique Book Chain Locket Necklace Victorian 800 Silver in Good Condition

This is a stunning antique necklace from an estate collection. It's a Victorian piece from the late 1800s. It's a heavy, ornate book chain with a large, layered metal locket. The locket has room for two photos; the inside has a protective insert on only one side. It's a beautiful piece for mourning jewelry, and would be amazing with a lock of hair tucked inside. The chain is 24" long, and the locket is 2.75" by 1.75" . It is heavy; it weighs 122g There are no maker's marks or metal purity stamps that I can find. It has been tested as 800 silver. It has been very lightly cleaned. It's in very good condition, with some minor signs of tarnish, patina, and wear.
