{"title":"Hubnerite","description":"\u003cp\u003e\u003cstrong\u003eHübnerite\u003c\/strong\u003e is a manganese tungstate, MnWO4, forming the manganese-rich end of the \u003cstrong\u003ewolframite group\u003c\/strong\u003e series with iron-rich \u003cstrong\u003eferberite\u003c\/strong\u003e. It typically forms elongated, bladed, or tabular monoclinic crystals with a submetallic to resinous luster, in shades ranging from deep reddish-brown to almost black, often showing a striking wine-red to cherry-red translucence when backlit. Crystals frequently occur in parallel-growth clusters perched on gemmy quartz, making them highly prized display specimens.\u003c\/p\u003e\u003cp\u003eThe classic locality for fine hübnerite is the \u003cstrong\u003ePasto Bueno\u003c\/strong\u003e district in Ancash, Peru, where mines such as the \u003cstrong\u003eHuayllapon Mine\u003c\/strong\u003e have produced world-class lustrous blades associated with quartz, fluorite, and rhodochrosite. Other important Peruvian occurrences include the \u003cstrong\u003eMundo Nuevo Mine\u003c\/strong\u003e in La Libertad. In the United States, the type locality is the \u003cstrong\u003eEllsworth (Mammoth) Mining District\u003c\/strong\u003e in Nevada, with additional notable finds from the \u003cstrong\u003eAdams Mine\u003c\/strong\u003e in Colorado and the \u003cstrong\u003eBlack Pine Mine\u003c\/strong\u003e in Montana, the latter also famed for veszelyite.\u003c\/p\u003e\u003cp\u003eCollectors seek hübnerite for its combination of vivid color, crystal habit, and mineralogical significance as a key member of the tungsten ore minerals alongside scheelite and ferberite. Fine Pasto Bueno pieces in particular are considered classics of the Peruvian mineral trade, valued for their aesthetics on quartz matrix.\u003c\/p\u003e","products":[],"url":"https:\/\/www.italmineral.com\/collections\/hubnerite.oembed","provider":"ITALMINERAL","version":"1.0","type":"link"}
