This is a puzzle! It is a Great combo piece containing 5 minerals. The most surprisingly spectacular are the blood red Wulfenite crystals in a prismatic habit, up to 1 mm in size sitting on a carpet of green velvet Malachite. Wulfenite is rare in Katanga (only 2 valid localities for this huge province) and in Musonoi they are at their best. They are associated with well terminated and bright yellow Kasolite crystals reaching 2 mm in size. Some are showing phantom growth. Also present are green, transparent platy Torbernite crystals reaching 4 mm on edge. The edges of the Torbernite are worth a closer look - some of them are the matrix for very small Guilleminite crystal clusters. Fantastic under the scope, you can look for hours to all what is hiding on this specimen. This specimen was recovered during the removal of the U-dump in the early 90s. Musonoi has ceased producing minerals since then. Musonoi is the Type Locality for Guilleminite. Take advantage of this offer because nothing is coming out of Katanga anymore since more than 15 years, except for Malachite and Chrysocolla.
