I have about 100 pieces of Native American Jewelry I need to know of any web sites where I could find out. I have tried Google, & there are a lots of sites I did try quite a few of them. Not a lot of info. I looked on Amazon & eBay for books to buy, There are not many, 2 I think & while I don't mind buying a book or two not at 25 & 40 dollars each. Thanks

Hallmarks of the Southwest by Barton Wright and any of Gregory Schaaf's books - American Indian Jewelry Artist Biographies are great books with a lot of resources and artist's hallmarks. A great place to start to look up Native American jewelry and southwest turquoise jewelry artist hallmarks.
