This is a beautiful and unusual gypsum specimen. The crystals are mostly long and prismatic blades with flattened hexagonal cross sections and slanted terminations. They are a pretty yet pale aqua green in color, with a luster that is vitreous in some areas and dull in others. A loupe reveals that the dull luster on some crystal faces is due to an overgrowth of extremely tiny gypsum crystals, many in tiny radial clusters. There is a base which appears to consist of more gypsum crystals, although they appear dirty and do not have the color and transparency of the larger crystals. Also, it is clear that these crystals formed in a crevice - the contact surfaces on both sides are clearly visible.
