This cabinet-sized specimen consists of a large cluster of heavily-intergrown Apophyllite and stilbite crystals that rest on a basalt base. These Apophyllites are generally in good condition, showing noticeable damage and cleavage, but most are intact. They reach lengths of up to 1.3" (3.3 cm) and have excellent tetragonal prismatic form, with well-defined edges, clean faces, and well-formed pyramidal terminations. All are colorless, have a bright pearly luster, and are transparent to translucent. Most have very clear terminations, but rather cloudy prism areas. The accompanying stilbite blades are not as large as the Apophyllites, but are generally in better condition. Their monoclinic bladed form is very good, and all have a creamy-white color and pearly luster, and are translucent. Both minerals are separated from the basalt base by a layer of drusy quartz (made up of tiny crystals) that covers a layer of agate.
