Treasure Hunting For Turquoise
By David Cowley

Turquoise is possibly the most valuable, non-transparent
mineral used in jewelry.  It has been mined since at least 6000
BC by Egyptians.  Like other opaque such as coral, turquoise is
commonly sold by the size in millimeters rather than by weight.

Turquoise is usually found sandstone layers and can be seen as
splotches or as a network of brown or black veins running
through the sandstone.  There are many small-scale mining
operations that are worked by hand.  Only one mine in Apache
Canyon California operates at a commercial capacity today.

With a hardness of just under 6, about the hardness of window
glass, this gemstone takes a good polish.  It comes in white,
blue, green, brown, yellow and all of the shades in between.
The value of the turquoise you will find is determined by the
richness of color.  Robin’s egg is usually the most valuable.
The more of a green hug or lightening of color will decrease the
value.  Turquoise should never be soft or chalky in color.

Turquoise is typically found in the arid regions of the world
and some high quality gemstones have been found in the Southwest
United States such as Arizona, California, Colorado, New Mexico
and Nevada.

More that 120 mines have produced significant quantities of gem
quality turquoise in Nevada.  Nevada mines are primarily worked
for the gemstone as apposed to other mining areas where
turquoise is usually the result of the by product of other
mining activities.  The geological formation of Nevada

treatment or enhancements to be used in jewelry.

The mines in Royston have been in operation since 1902 and by
