A light brown to light gray,
crystalline muscovite matrix hosts several glassy
fluorapatite crystals to 7 mm; these display a modest
yellow fluorescence under shortwave UV. Sublustrous
arsenopyrite to about 1.2 cm, quartz to 1.1 cm and minor,
scattered calcite are also noted. Overall condition is
very good for this example typical of the
species/locality.
