Boulder Turquoise is sometimes referred to as Ribbon Turquoise, is found originally Royston Mines, near Tonapah, Nevada. Boulder Turquoise is comprised of Jasper surrounding ribbons of Turquoise making it very dense and such a rare find! It boasts the most beautiful coloring with rich browns along with shades of teals running throughout. Each stone is very unique in its patterns and color variations, making our Boulder Turquoise pieces even more desirable! Not to mention subtly stunning in every way! Stone on each earring measures around 1.25 inches. Artist Stamp J. TSO.
