caption_attribution_description: English: Richterite Locality: Wilberforce, Monmouth Township, Haliburton County, Ontario, Canada (Locality at mindat.org) Size: miniature, 4.4 x 3.1 x 1.2 cm Fluor-richterite Just a darned fine example of this rock-forming mineral, with good lustre, good sharp termination, and good form. You almost never see these occur so beautifully-crystallized and so the mineral is often dismissed as non-worthy of a fine collection. The cluster is also a floater.

context_page_description: Richterite is a sodium calcium magnesium silicate mineral belonging to the amphibole group. If iron replaces the magnesium within the structure of the mineral, it is called ferrorichterite; if fluorine replaces the hydroxyl, it is called fluororichterite. Richterite crystals are long and prismatic, or prismatic to fibrous aggregate, or rock-bound crystals. Colors of richterite range from brown, grayish-brown, yellow, brownish- to rose-red, or pale to dark green. Richterite occurs in thermally metamorphosed limestones in contact metamorphic zones. It also occurs as a hydrothermal product in mafic igneous rocks, and in manganese-rich ore deposits. Localities include Mont-Saint-Hilaire, Quebec, and Wilberforce and Tory Hill, Ontario, Canada; Långban and Pajsberg, Sweden; West Kimberley, Western Australia; Sanka, Myanmar; and, in the US, at Iron Hill, Colorado; Leucite Hills, Wyoming; and Libby, Montana. The mineral was named in 1865 for the German mineralogist Hieronymous Theodor Richter.
