It would appear that many of the Harmotome crystals that erupt from the base rock of this specimen are not twinned! I see several monoclinic prismatic crystals that seem to be individual, without any of the symmetry that would signify twinning. Others, however, are obviously twinned, and some of these have a seemingly hexagonal prismatic form. The largest of these crystals has dimensions of 0.4 x 0.4 x 0.2" (1.0 x 1.0 x 0.5 cm), and shows only a small amount of damage along its edges. Other crystals are almost as large, but are heavily damaged and usually incomplete. Crystals range in size down to 1 mm or less in each dimension, and tend to be in generally better condition as their size decreases. They are milky-white and have a vitreous luster. Some crystals show small portions of transparence, but these are spoiled by intense internal fracturing, which I believe contributes to their color. They rest on a rather nondescript gray-green, igneous host rock that shows a few veins of either calcite or more, massive Harmotome.
