Opera Length Fresh Water Pearl Necklace, 91'' Necklace.....Our dramatic 91'' fresh water pearl necklace features a continuous strand of of 8mm black pearls. They are individually knotted and as you can see in the pictures they are very rustic. I believe them to be color enhanced and they cast a luminous black grey to plum purple color. It is just gorgeous and can be worn a variety of ways. This estate necklace is in good condition with age appropriate wear.
