Bob Hall can be considered a geologist, historical architect, and jewelry designer all in one. He has traveled to many parts of the world to find rare stones including Asia, Australia, Mexico, and the American West. His knowledge of geological factors involved with mining semi-precious stones is extensive.
Bob Hall currently works holdings in Wyoming, Nevada, and Arizona, extracting turquoise, garnet, amethyst, and jade. Jade, believed for centuries by the Chinese to bring harmony and good fortune, constitutes a major portion of the jewelry Bob creates. Amethyst, turquoise, garnet, and fossilized coral are among other stones Bob uses in design.
Bob Hall sometimes spends 40 to 60 hours just polishing beads with sandpaper, increasing from 300 to 3,000 grit in texture. The time he spends perfecting the works of art is evident, as all his pieces are truly one of a kind and exquisite.
