American Turquoise

The Hartman’s of Durango, Colorado have been involved in the Turquoise business for well over 40 years and have become among the few actual authorities on the subject. It goes way beyond money for the Hartman’s as it has engulfed their lives and their world has been surrounded by this wonderful gemstone. John and Estell Hartman were enthusiasts growing up as kids and John gave Estell her first piece of Turquoise when she was only 13 years old – so it runs very deep in our origins.

Our lives together were surrounded by this fabulous gemstone and we believe that it has had much more of an impact on our lives other than money. We are not the religious type of people, yet we have been blessed with good health, happiness and fortune all of our lives. Looking at our past and the prophesies of past healers of the world – it stands to reason that Turquoise may have inadvertently had metaphysical and spiritual powers that have been bestowed upon us as well as our family.

We hope you will think of Durango Silver Company for all of your Turquoise information and needs.
