Here is a heavy yellow gold filled link chain with a fob that has butterfly wings on both sides. This chain is from the late 1800"s/ very early 1900's. Measures 13 inches from top to bottom. T bar at the top and locking swivel at the other end. Near the top is a shorter chain that has a round fob with butterfly wings on both sides. Chain shows some wear if you look closely so it was used but not bad. Each link measures 6 mm wide and 2.5 mm thick.
