This 3 cm. chunk of Albite and Quartz matrix contains a tiny gemmy 1 mm. Spessartine crystal and two anhedral pink Apatite crystals (roughly 1 cm.), which in normal white light can barely be seen. Just left of center and near upper right corner. However, when I switch on the shortwave UV light, they fluoresce a brilliant yellow. (See second and third photos, below.) The specimen was collected in rubble on the southern slope of Aguanga Mountain directly downhill of the adit of the old Maple Lode Mine, which currently is fenced and posted. It almost certainly eroded out of the pegmatite above.
