I would suggest checking your local library for books on Silver Hallmarks of the Southwest. I believe there are at least 2 rather large books that cover this field. I am not familiar with Julia Etsitty and she could well be an American Indian. Good luck in your search and get back to us with your results.
Hi Dave! Not sure if you still own this bracelet. I have a gorgeous bracelet by Julia as well and have tried to find info about her. Do you happen to have a picture of the bracelet. I can send you a pic of the one I have. It would just be great to see more of her work.
