Navajo/Zuni solid sterling silver cabochon turquoise gemstone charm bracelet

A charm bracelet with 7 charms.
 
The bracelet is entirely solid sterling silver, the chain, clasp and charms and the clasp is brand new but goes well with the piece, the clasp is a tad strong as it is new but it will get better and easier to open as it is used by the wearer. 
 
The charms are as follows; a broken arrow, a horse that is stylised, a North East South West charm, an Indian chief, an eagle, a tortoise and an arrowhead. Each of the charms has a turquoise cabochon.
 
This piece is vintage and the turquoise has taken on a more green colour as Vintage turquoise can, the turquoise is natural turquoise without gem treatment.
 
The piece is not just the style of Native American Indians but it is indeed made by either Navajo or Zuni and I am leaning to Navajo though being a charm bracelet it is a piece of jewellery that is made to the style of Western jewellery.
