This large hand specimen consists of several Apophyllite crystals which rest on a crystalline quartz crust. The largest of these Apophyllites has dimensions of 0.9 x 0.9 x 0.6" (2.3 x 2.3 x 1.5 cm) and is rather badly damaged and broken in one area; two other crystals are damaged, and one of these shows obvious cleavage. The other crystals are generally intact and in excellent condition. All have excellent tetragonal prismatic form, with well-defined edges and clean faces that possess the standard bright pearly luster. Their basal faces, however, have a rather dull pearly luster and are very subtly patterned. All are colorless and dimly transparent due to many cloudy inclusions and basally-oriented internal cleavage planes. They rest on a crust or druse of small, well-formed quartz crystals that do not exceed 0.3" (8 mm) in either length or diameter. This druse covers a thin crust of gray banded agate that partly coats the basalt base rock
