A fine, old-time, large cabinet calcite specimen from the Joplin Field of Missouri. Two striking, intergrown calcite scalenohedrons to 12.5 cm are beautifully set on a very sculptural silicified limestone matrix that is nicely accented with a field of dolomite rhombs and a rich scattering of lustrous, brassy marcasite crystals. The translucent, amber calcites have gemmy terminations and their bodies are partially overgrown with a second generation of white calcite. The calcites are complete-all-around and the terminations are pristine. Ex. Mullane Collection.
