Featured Bone (?) Thingamajig

Bought this item ...and have no idea what it is...

I thought it could be some kind of Stanhope item due to the hole in it (even though it was already clear that there wasn't a microphoto in it), or a needle holder, but it isn't hollow...

It's made up of 3 parts. Unfortunately one part can't be screwed onto the middle part. Not sure if it was broken or if some kind of glue/resin messed up the thread.


It was sold as being ivory, but based on the blood vessel lines and dots, and the lack of crossed lines, I assume it's bone.


So, can anyone tell me what this thingamajig is?

 

it's a Whatyamacallit...
& ya..bone !

 

I know nothing about whatever this may be....... that said, for some reason a child's fidget toy comes to mind. Just pure speculation.

 

The Chinese have a saying; Wisdom begins with calling things by their proper name.

 

Now I wonder if it could actually be a needle holder, with this part

being hollow, and that the hole has been blocked off by that red substance...
