Help Identifying Item, Please

The amethyst colored bauble type ends unscrew completely and are removable. The hinges allow full movement.

We found this pair in my great grandmother's jewelry box, which puts it somewhere between mid 1800's to early 1900's.

See pictures for scale*. Any help would be appreciated. So far everyone that has seen these is stumped.

*pictures aren't uploading to this thread, but I was able to save them in an album. Please click on my name and view the pictures in the album. Thanks!

 

Have no idea what those are

A close up picture and one of the back might help

 

Could they hold something something closed but yet be adjustable or at least flexible? A cape maybe?
