This sterling silver White Buffalo cuff is signed Boyd J. Ashley, a Navajo silversmith whose work includes gemstone jewelry with detailed stampwork. The polished centerpiece has a softly triangular outline, with a predominantly black surface crossed by sweeping ivory-white bands and fine pale veins. A smooth bezel follows the stone’s irregular shape, setting it prominently above the band. Repeating leaf-shaped motifs and radiating stamped accents decorate the open cuff, their dark recesses standing out against the softly patinated silver. The substantial centerpiece and strong black and white contrast give the bracelet a bold, confident character.
