Dioptase on calcite
description: <p style="text-align: justify;">LOCALITY: Tsumeb, Namibia <br /><br />4 1/2" across <br /><br />The largest crystal is just short of 1" long <br /><br />Refer to the illustration on page 85 of "50 Year History of The Tucson Show" published by "The Mineralogical Record" in 2004. The illustration is of a showcase of elite specimens of dioptase exhibited at the Tucson Gem and Mineral Society Show during the 1980's. At this time, Tsumeb was still producing dioptase. <br /><br />Critical evaluation of my pictured specimen against almost all of the pieces in the illustration on page 85, would lead to my piece being judged as better.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">This piece was bought from Doug Wallace of Dallas, Texas at the Denver Show in 2009.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">Photo by Matthew Webb of Melbourne, Victoria, Australia   </p> <p style="text-align: justify;"> </p>
