Fill-in Necklace By Napier This is a fun filigree “fill-in” necklace by Napier that dates c. 1950s to the early 1960s. This twisted chain and bead motif was used virtually every decade from the 1950s to the 1980s. It was a timeless design that could complement any tailored collection by changing the bead color and size with different chain styles, including link and mesh chain. The clips on the clip-back earrings are seen more during the 1950s, with a few designs utilizing this clip in the 1960s.
