Calcite, Chalcopyrite and Dolomite  Sweetwater Mine, Viburnum Trend District, Reynolds County, Missouri.  This piece is exceptional exhibiting two transparent calcites of 3.9 and 3.4 cm each.  They are double terminated and stand of the well crystallized matrix in nice relief.  The piece is much better than it appears in the images and is damage free.  It stands nicely on end for display and is a damage free floater.   5.4 x 5 x 5.3 cm overall.  Spotless!  My price reflects the outstanding deal I received on this fine specimen.  An American Classic that was wrote about in American Mineral Treasures, 2008, p. 66-73.  75$
