This display piece consists of a large section of compact, columnar Ulexite. As is usual with this mineral, no definite crystals are present, but its crystalline tendencies are obvious. It has a grayish, milky-white color and a dull, silky luster along its length, and is dimly translucent. One small area shows brighter white color and fibrous, radiating tendencies. Even in its rough state, there are one or two areas that exhibit its inherent "fiber optic" properties. Only a small amount of a dull, gray-black host material is present.
