Cryptomelane is one of the manganiferous products designated under the generic name Psilomelane. This is “Psilomelane potassium”, potassium can be very partially replaced by other elements, notably Thallium. It is found in the superficial parts of rocks and manganiferous deposits. Its name is derived from the Greek kruptos (hidden) and melanos(black) because this mineral was difficult to identify among the other Manganese oxides, also black. Cryptomelane usually occurs in earthy or compact masses, steel gray blue to black, staining the fingers. Like most Cryptocrystalline Manganese minerals, it tends to evolve into well-crystallized species (Pyrolusite and Magnetite).\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan class=\"s1\"\u003e\u003cspan\u003e\u003cbr\u003eCombination:-\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan class=\"s1\"\u003e\u003cspan\u003eThe Cryptomelane typically forms a stark contrast against the Scholzite, appearing as dark grey-to-black botryoidal (grape-like) micro-spheres or coatings. \u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eCryptomelane commonly manifests as a second-generation mineral coating over the pre-existing Scholzite crystals with rounded Cryptomelane spheres scattered directly across or perched on top of the elongated, sword-like Scholzite needles.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"NaturesgiftsByChris","offers":[{"title":"Default Title","offer_id":50303166742805,"sku":null,"price":24.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0870\/2453\/3781\/files\/IMG_6321_4924ef7b-7c04-4c40-a481-6097425a863d.jpg?v=1792649397","url":"https:\/\/naturesgiftsbychris.com\/products\/46g-scholzite-with-cryptomelane-specimen-a-from-south-australia","provider":"NaturesgiftsByChris","version":"1.0","type":"link"}
