What kind of Pearls are these?

[Sheenabalina]

I have a bracelet and necklace made of the same pearls from a long time ago I just dug out of storage. What kind are they and I am trying to also find out what the possible worth is for them?

Rice Krispie pearls! Early Chinese freshwaters.

They don't have much market value but can be fun to wear.
