Help Identify Vintage Pearl Bead?!

[LauraJewelsMary]

I found a few of these amazing looking vintage beads, I believe they are some kind of pearl & I also have some in a red that are very similar! I have no clue!

Can you please post more photos-- more of the beads, too--on a white background (a paper towel is good). In focus, no flash, please.
Also try rubbing 2 of the same beads together; what do you feel? Smooth, or gritty?

Also, beads that are red are either dyed pearls or not pearls.

They look like stone. Maybe some type of jaspis.

Please post a photo of the other beads, including the red ones. These may be dyed mother of pearl and can be very eye-catching.

Okay! I'll be home tomorrow and I'll post more pictures of them!! They are gritty just like a pearl and looking inside the hole they seems like flakey layers if that makes sense! lol Thank you everybody that has responded!! I've been helping a friend so I'm just getting time to check this now! Normally Google image search will show me something similar to what I have but I have searched for hours on end and found nothing that looks like these. They are SO gorgeous and unique! I wanna make stuff with them but I wanna know what to call them! haha
