Description of Haskell construction

Want to list this baroque pearl necklace by Miriam Haskell, but need some help describing the gold bits; does filigree cups apply?  According to RCJ this tag could be as early as 1950-51. 

Thanks so much!

Wonder if  Petaled Bead Caps  would apply here?  I`ve seen that term used in online suppliers

Oh, I like that!  Just searched RL and find that term associated with Haskell.  Thanks!

They are also known as clamshells.

Sorry, for some reason the first pic didn't show up and I was commenting on the end caps - not the filigree ones.

This is an interesting necklace. It all looks good for Haskell but the end caps. I remember being informed that Haskell did not use or rarely used them on her beaded pieces.

That being said it looks like #10 here possibly has end caps:
