Vintage 1928 Blue & Black Dainty Necklace

Reposhing this item I purchased from @sewmom10. Loved it, but ready to rotate for something new. It's a short necklace, resting on the collar bone on me. But not quite a choker. It's in the exact same condition in which I bought it, which is gently-loved. The stone below the heart is either missing or it's not supposed to have a stone (as the metal is so shiny). If the former, it's not noticable. It's definitely at least 1990s in terms of age as it's chain is in an older style than more recent blue/black jewelry from this company. Could be older. Really a lovely little gem of a necklace. Questions? Leave a comment below!
