This 22” strand of natural freshwater pearls was bought for my birthday 60 years ago in India. They were sold by a trusted jeweler. They were strung without a proper catch as he purchased them loose from a newab’s collection. I have been trying to find out how to get an idea of what they might be worth. None of the jewelers in my town know anything about natural pearls, only cultured ones. I realize I could send them to GIA, but I really would rather not do that unless I decide to sell them. Any ideas? (I took these photos outside on a grey day. If there’s a better way, please let me know and I can take new photos)
