Definitely silver! As you can guess, this is hand-made - more than likely Navajo. Definitely Navajo style.
The buckle itself is hand-made, the bear and leaves are bought from a "jobber". I'm thinking that the silver "beads", for lack of a better term, are also "jobber" supplied - maybe not. Non of that decreases the value an any way though.
Everything else is hand-made by a silversmith. The name on the back is the name of the silversmith that made the buckle. It is a Navajo tradition for the silversmith that creates his work to stamp/engrave his or her name on the back of whatever he or she creates.
As someone mentioned, the stones are definitely turquoise are coral. And I am going to guess here as I have been away from this for a VERY long time, but I will say that the turquoise is probably from the Bisbee mine in Arizona. Just a guess.
Everything being meticulously soldered to the buckle and the hand stamping around the border will tell you that this took some time to create. This a very nice piece!
Hope this helps, well done!
