VINTAGE NECKLACE, 20- 23" adjustable, Blue Flowers w/Rhinestone, Goldtone N24

20 - 23" Necklace with 28 blue stone flower like with Rhinestone in middle. It is in excellent used condition, but there is one blue petal stone missing. I just noticed it. I am going to try to find that stone but no guarantees, so if you buy it, you might have one petal stone missing. Goldtone on chain. I am sure this is not supposed to be reversible, but it totally could be. see pic.
