120+ year old graduated pearls with antique sterling clasp

I was given my Godmother's pearls, which are of a beige color. I am 52, my Godmother died in 1972. At that time she was 82. She was given the pearls as a young girl by her eldest sister. She was the youngest of 14 children; their mother died after the last child was born leaving the older siblings to raise the younger ones. I have no idea where her older sister orginally obtained the pearls from.
One thing I read on your website concerns me. You mention they should be knotted in between each pearl. These are not knotted, but are perfectly graduated.

What are your thoughts?

I'm not very good at uploading photos. If they are worthless since they are not knotted, that would be helpful to know.
Thank you.
