This single Aegirine crystal is in excellent condition, showing no human-induced damage that I can see. Its monoclinic prismatic form is very good, showing disseminated but definite edges and striated but clean faces that possess a vitreous luster. It appears to be completely black in coloration and is opaque. There is no host rock present on the piece, but a few tiny chabazite crystals rest near its termination, and what look almost like tubular calcite or dolomite formations rest on one prism face. The piece is hot-glued onto a flat, square acrylic base.
