Gray Freshwater Pearl Necklace with Sterling Clasp

Beautiful gleaming round 12mm gray freshwater pearls are strung to form an 16" necklace with a curvy Sterling Silver hook clasp. The pearls are rainbow hued and each are different, not perfectly round but close. This necklace belonged to a dear aunt who evidently purchased it during one of her Asian travels. I know she said they were freshwater, not cultured or Tahitian and described their color as silver gray. They are magnificent.
