Mineral Specimen #5162 Hydroxylapatite, Muscovite, Microcline, Quartz
Sapo mine, Ferruginha, Conselheiro Pena, Doce valley, Minas Gerais, Brazil
This specimen consists of numerous crystals of Hydroxylapatite on Microcline. Hydroxylapatite is considerably less common than Fluorapatite. Additionally, the crystal habit exhibited on this specimen is quite unusual for Apatite being flattened, curved, hexagonal bipyramids. The color is a rich sea green with a slight hint of blue. The color varies shading into a lighter, more yellow green color which is found in the middle of the crystals. The color of the Apatite contrasts nicely with the underlying Microcline which is a light peach, orange/pink color. Also present are dark colored Muscovite crystals.
Flaws: There is some chipping on the edges of some of the crystals. There is the base of a broken Quartz crystal in the middle of the crystal which is not noticeable.
7.4 x 4.4 x 3.5 cmThe largest crystal is 1.4 cm long.
