The Ajax mine is a new, small mine located in south central Nevada in the Royston area.  The mine yields stones from light blue with darker blue veins to a predominate dark green with light blue areas. 
The presence of Iron turns the Turquoise green.  Most of the Nevada Turquoise is green, and Ajax produces some of the finest specimens of both colors, sometimes combining both in the same stone. 
The coloration of dark green and light blue is quite rare for turquoise.   A highly collectable active mine.
