A classic, old-time, complete-all-around specimen of sceptered calcite from the Blackstone Mine, Shullsburg, Wisconsin. The grayish-tan scalenohedron is abundantly overgrown with lustrous 1 mm - 1.7 cm rhombohedral calcites in parallel stair-stepped growth. The scalenohedron is capped by a transparent and lustrous, 6.0 x 5.5 cm, complex rhombohedral calcite crystal, which makes for a spectacular sceptered calcite specimen with a striking phantom. Ex. Dr. Gary Hansen Collection.
