Bright Orange Beads - Does Anyone Know What They Are?

Hi everyone! Long time no see! Real life has kept me away from posting and reading the Boards. I was wondering if someone can help me with these unusual bright orange beads.
I purchased these at an Estate sale on the North shore of Long Island because I thought the color and look of the beads was interesting.
They look like they can be a natural material, but, I'm not sure.
The string that they are strung on seems old and the beads are cold and quite heavy.
Any thoughts? Thanks everyone!

 

Hi, Tonettedogs -- good to see you. I don't know the answer, but hope that somebody will come along who does.

 

Could you get a close-up of a couple of the beads? The color looks dyed.

 

Thank You Fig..good to see you too! I'm adding some close ups with the hope they look familiar to someone.
At first I thought they were glass beads. Upon closer inspection you can see inclusions and variations in color, which makes me think they might be a natural material.

 

Maybe bone?

 

Thank You moreotherstuff for taking a look!

 

I didn't think of bone. Would bone be very heavy?

 

You'll have to wait for someone more experienced than me.

 

Thank You! These really have me stumped!

 

Hi,
Welcome back. These make me think bone from India. it might be the twine making me think that but JMHO

Thank You, Greg! I'll look in that direction too!

 

They look like Prosser/Kakamba glass trade beads.

 

They're a different shape than the ones I've seen, but I think Anund nailed it.

 

Thank You so much for solving this mystery, Anud! I really appreciate it!

 

Never heard of Kakamba Prosser beads, but seems to be correct. Here's some info:

They look like dyed howlite or from a similar stone..

For your consideration is a vintage Antique African Trade Bead Six Strand Necklace.

Bright orange color strung on very old twine like string.

I was told these are very rare old beads. Possibly Kakamba Prosser beads.

 

Um, Shiloh - that's her listing.
