At least 6 small Brookite crystals rest on the crystalline quartz base of this thumbnail specimen. Two of the smaller crystals are broken and incomplete, but the largest ones are intact and in excellent condition. They have a rather odd octahedral form that is common for Brookite from this locality- two opposing corners on each crystal are flattened so that each appears nearly tabular in form. Otherwise, their edges are well-defined and their faces are heavily patterned but clean. All have the standard black color and a slightly dull adamantine luster. The base on which they rest is made up of at least 3 intersecting quartz crystals that resemble "elestial" quartz in form, with small multiple terminations and growth patterns. They have a gray color and a dull, waxy luster.
