Vintage Cultured Pearl Necklace

I bought this beautiful necklace in Italy about 21 years ago. It’s in almost excellent condition. The clasp feels lose but can be tightened. It won’t come off when you are wearing it since there is another way of securing it as pictured. There is a slight discoloration on the clasp as well which is not visible when wearing it. It comes with this beautiful earrings (not pictured). I bought it separately but will give it as a free gift with this purchase.
