This cabinet-sized specimen consists of scores of Apophyllite prisms that line the inside of part of a basalt vug. These crystals are generally in excellent condition due to the protective form of their host, and reach maximum dimensions of 1.4 x 1.3 x 0.9" (3.6 x 3.3 x 2.3 cm). All have excellent tetragonal prismatic form, with well-defined edges, clean faces, and well-formed and truncated basal terminations. They are generally colorless, transparent, and have the standard bright pearly luster. Most are very clear, but the largest crystal (which is much larger than the rest) is quite cloudy, containing many cloudy inclusions and several internal fractures. They are accompanied by many stilbite blades, most of which are broken, and are separated from the basalt host rock by a thin layer of gray-white agate.
