description:
Neat specimen for the species, this a large open geode lined pocket lined with glistening black crystallized pyrolusite. In great condition. The specimen comes with a previous label from the collection of Jan Erik Larsen.

The Imini mine, located in Ouarzazate Province, Morocco, is a world-famous mining area renowned for its Cretaceous-aged sedimentary manganese oxide deposits embedded in dolomite and sandstone. Discovered in the early 1900s, the locality saw extensive underground and open-pit mining operations through the 20th century, becoming one of North Africa's primary sources of high-grade manganese ore. Today, it is equally celebrated among mineral collectors worldwide for producing exceptional, highly lustrous crystal clusters and velvet-like fibrous coatings of various manganese minerals, particularly pyrolusite and ramsdellite.
