Betsey Johnson Blooming Pearls Butterfly Necklace

Hi there, up for sale it's a USED Betsey Johnson Statement Necklace from her Blooming Betsey Collection. The chain still looks very good. Minor signs of wear. There are no rhinestones missing. Pearls are in great condition. However, there are two links in one the chains that appear black (like paint). I have no idea how this might have happened. Also it is more noticeable on the back side of the chain and it is less noticeable from the front view of the chain. The last two pictures show this specifically. If you have any questions or need additional pictures please let me know. I try to respond within 24 hours. Thank you so much for looking.
