Unusual vintage 14k yellow gold chain with "S" shaped twisted links. The heart pendant is gold filled. Each hand-made chain link is twisted in the middle and linked to the next. It measures 16" long and the clasp is completely removable. The chain is unmarked but has tested as 14k, the heart is unmarked but does not test as gold. The heart measures approximately 1 1/8" wide and 1 1/2" tall (including the bail). It looks like a locket, but does not open.
