Can anyone identify the artist of this amazing Zuni cuff bracelet?

Can anyone identify the artist who made this apparently Zuni bracelet. It is 1 7/8 inches wide and fits a 7 1/2 inch wrist.
The mosaic plaques are 1 1/2 inch square and the horny toad (horned lizard) is over 2 inches long and over 1 1/4 inches wide across the rear legs. The workman ship is superb and the photos don’t do it justice. There is no hall mark but it is stamped sterling in the center of the back.
