Vintage Blue Thread Wrapped Bead Necklace Gold Tone Accent Beads 31"

I am not able to identify the maker of this necklace, this is used and have a little bit of yellowing/staining on a few of the beads.  Please see the photos.  There is also a little space from wear but does not affect the look of the necklace. 

Please let me know if you have any questions
