This is an antique memorial locket on a 28 inch long tiger eye stone necklace chain. The locket is unmarked. The metal is rose gold in color and is marked rolled gold on the bottom edge. The locket has clear celluloid covers over both sides. I have not opened the locket. There is a tiny peg or pin through the neck below the bail loop, and it appears that the peg needs to be removed in order to open the locket from the top and insert photos of your choice. I would suggest having a jeweler do this for you.
The locket measures 1.125" x 1.375", excluding the bail. The chain is 28" long and has no clasp.
Condition is overall good. There is a worn spot on the fabric inside the locket, near the top.
This is a nice long chain to carry your memories upon.
