Zuni Disney Character Jewelry

Are there any collectors in this forum that specialize in early handmade Disney pieces. My wife has a number of very beautiful, well crafted and exciting Zuni Silver pieces inlaid with coral, turquoise and other simi-precious stones. Some are signed but most are not. We have had difficulty finding information on these pieces.

I have some pieces made by Veronica Poblano, Sulliban Shebolo, Carol Lasiloo and Amelio Nastacio(without Veronica).

Recently I saw some of the above-mentioned jewelry here http://www.pricescope.com/wiki/wholesale-diamonds

Pictures would help identify the pieces.
