Willie Yazzie started making silver overlay jewelry in the 1950's when the more well known Hopi smiths were doing the same. He worked from then until the 1990's. He was a teacher and silver smith at Mesa Verde National Park from 1960 to 1983. His wife also did similar silver work as does his son. In my humble opinion, he and his family have not been properly recognized for their early and important contribution to overlay technique.
This bracelet is probably from the 1960's or so, it depicts a turtle and other symbols. 5 5/8" inner circumference PLUS a 1 3/4" gap. 1 1/2" wide, hallmarked by the artist. Excellent worn condition.
