2 SW Silver Bracelets; a Coral & a Turquoise: Unsigned

There isn't a signature or other mark on either. Does the style or any other feature suggest an area or tribe? These an' the two rings just posted are part of the costume jewelry hoard belonging to a friend's wife, who is in memory care. Eventual sale of all this stuff will assist him to pay for that care. Thanks for your help, an' for lookin'!

 

both easily look Navajo....... BUT..... no siggy , uneven workmanship... leads me to think otherwise...!
