I recently purchased a turquoise bolo. The hallmark that I found is :AZ9AY
My research shows that this belongs to Arthur Yazzie. But I cannot find any additional information about him, except his birth and date of death. Where might I find additional in formation about his life, work and perhaps the time at which he was making jewelry?
I believe that the hallmark indicates that the stone in from the Kingman mine in Arizona, which would match the color of the one that I purchased.

I recently purcased a concha belt in Santa Fe with the same trademark. If you do find any more info, please let me know. What were the dates of his birth and death? Thanks, Carol Meyers, [email protected].
