I have a pair of sterling and turquoise earrings that are marked E. la?? Zumi N.M. etched in like writing and then a stamped mark that is a V with feathers off the outsides of the V. Does anyone have an idea of who the artist is or the store these were gotten from. Or are they fakes? Thanks

There is a website. I can't do links now. Try typing native American hallmarks in browser. The one site is southwest in the web address
