This vintage necklace is made with a New Zealand 1960 Queen Elizabeth II one penny coin. The coin is adorned with rhinestones and hung from a mixed media necklace made with pearls, rhinestones, cord, metal chain and a large smoky quartz stone (simulated I believe). I believe the coin to be authentic bronze. The necklace is in very good vintage condition. The pearls show some signs of wear if magnified. I looked over the internet and could only find one similar to this, so rest assured, it is most likely one of a kind. It is approximately 16 inches in length.
