Prominent parallel striations extend across the crystal surfaces, creating a distinctive fibrous and bladed appearance. Several overlapping crystal groups display different orientations, producing attractive variations in reflectivity and texture. Small patches of reddish-brown iron staining contrast with the bright metallic surfaces, highlighting the specimen's natural formation.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eManganite is a manganese oxyhydroxide mineral, MnO(OH), recognized for its dark coloration, metallic to submetallic luster, and characteristically striated prismatic crystals. It commonly forms in low-temperature hydrothermal environments and through the alteration of other manganese-bearing minerals. The historic Lake Valley Mining District of Sierra County, New Mexico, is best known for its silver deposits but also contains manganese mineralization. This vintage-labeled specimen represents an interesting example of the district's mineralogical diversity.\u003c\/span\u003e\u003c\/p\u003e","brand":"The Crystalary","offers":[{"title":"Default Title","offer_id":67977992994947,"sku":"barrydwr5-1of2-140","price":59.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0390\/4634\/8931\/files\/IMG_37582.jpg?v=1792524719","url":"https:\/\/www.thecrystalary.com\/products\/gold-bearing-unverified-black-sand-gaffney-cherokee-county-south-carolina-usa-copy","provider":"The Crystalary","version":"1.0","type":"link"}
