RM3057   Columbite-(Mn) and Albite

Shengus, Haramosh Mts., Skardu, Gilgit, Baltistan, Pakistan

In this specimen we can enjoy different columbite crystals, one of them predominant, although there are smaller, transparent and reddish ones. The analyzes of the specimen indicate the majority presence of niobium and manganese, so it is a columbite-(Mn) (you can check analysis in pictures). The main crystal stands out for its faceting, it has a small dent without affecting the quality of the piece. It comes from the collection of Michel Jouty (1930-2016).


Size: 5.7 x 5.4 x 3.8 cm.
