Aquamarine, a gem variety of the mineral beryl, is the official state gemstone of Colorado. Aquamarine from Mt. Antero, Colorado were first introduced to the mineralogical community by “Nels” Nelson Daniel Wanemaker in 1885. The launching of the Weather Channel’s Prospectors show in the first part of 2013 was great publicity for the Colorado Aquamarine .
