Scores of Aegirine prisms, spikes and needles permeate the feldspar host of this large hand specimen. These crystals reach lengths of nearly 2" (5 cm) and are generally in excellent condition, though several of the finer ones are broken. All have good monoclinic prismatic form and have a brown-black color and vitreous luster. They are more or less completely opaque. The host material is made up of countless albite platelets that are intermixed with several microcline crystals, most of which are incomplete or warped.
