Mineral: Fluorite
Locality: Erongo Mountain, Usakos, Erongo Region, Namibia
Dimensions: 24 x 18 x 34 cm / main crystal: 4.5 cm

Description: Mass: 9000 g MIM number:1908 Block made of microcline crystals twinned after the Carlsbad law (up to 6 cm) and schorl (up to 7 cm) covered with well separated cubic and transparent fluorite crystals of an astonishing emerald green color creating a beautiful contrast with the microcline. The cubes of fluorites have beveled faces; some are traversed by fine schorl crystals. The microcline and schorl were formed first and then leached by the hydrothermal fluids which left them in this altered condition and subsequently deposited the fluorites.
