Lead Crystal Depressed Diamond Necklace with a sterling silver chain. Measures 2 1/4" from top to bottom, not counting the bail. The sterling chain is marked on the clasp and the clasp finding, and measures 23" long. I believe the bail is also sterling as it shows a tarnish typical of sterling. It could be worn as is or polished back to its original shine. A very light roughness on the edge of the diamond tells me this is cut lead crystal. Condition is excellent.
