Emplaced on matrix are several SHARP, waxy and translucent, tan-colored, calcite rhombs to 4.5 cm across. This specimen is special because it appears to feature two separate laws of twinning, penetration and rotational. In addition to the twinning, this unusual calcite specimen also appears to be pristine. The multiple penetrations and sharp resulting form of these crystals is nearly unique, and I recall this find coming to market in the late 1980s - and then nothing else afterwards of the same style. Overall, the piece is very 3-dimensional and well balanced, in line with Richard Heck's consummate taste in mineral specimens
