Found this great Napier collar necklace at the thrift, anyone know when it was made?
Anyone have guesses on when it was made? It doesn't have the circle copyright symbol that would have appeared in 1955 but I read Napier was a little inconsistent about that and didn't always include even after that year.
The foldover clasp doesn't help either, I feel like it could be mid century all the way through the 80s/early 90s haha.
Really pleased with this one regardless! It's so fun.
