Monet Vintage Gold Tone Omega Chain Crystal Choker 16" Necklace

Monet Vintage Gold Tone Omega Chain Crystal Choker 16" Necklace. Pre-owned, this vintage necklace is in excellent condition. There does appear to be glue or something near the clasp. I have tried to remove it, but it won't budge. It appears to have been put there to secure the clasp to the chain, and it is secure. Fold Over Clasp. N469
