Mineral Specimen #4852 Quartz on Siderite on Microcline Stalactite
Mt. Malosa, Zomba, Malawi
9.7 x 4.8 x 4.7 cmThe second and third dimensions were taken at the widest points of the specimen.
A stalactic stack of off white colored Microcline crystals partially covered with small crystals of Siderite and Quartz. The Siderite ranges in color from orange/brown to black with the black crystals having a high, sparkly luster. The Quartz crystals range in color from clear to off white to slightly smoky. Please note: to all appearances, these are Microcline crystals, although, Orthoclase is also found at the location. Both are chemically the same with different crystal sructure. These do appear to be monoclinic rather than triclinic.
Flaws: Nothing Appreciable
