Sterling Silver 42 Inch belcher Chain that has a mark on the silver circle where the clasp should be (No actual clasp). I think the chain may be European. There is a Sterling Silver 2 3/8 inches long Perfume flask on the chain which can be unscrewed at the top, and there is a silver 'applicator' inside this. The perfume bottle is marked TC-60 925 Mexico. The necklace is quite different, and the chain can be used for many different looks.
