While magnetite typically forms in octahedral shapes, the Balmat specimens often display dominant cube faces, sometimes with subtle tetrahexahedral modifications, making them exceptionally unique. The cubic magnetite specimens from Balmat, New York were discovered in 1991–1992 during mining operations by the Zinc Corporation of America at the Empire State No. 4 Mine (also known as ZCA Mine No. 4) near Sylvia Lake in the town of Fowler, St. Lawrence County, New York.

The Tsumeb polymetallic (Copper-Lead-Arsenic-Zinc-Silver-Germanium-Molybdenum) deposit contains one of the most diverse examples of mineralogical paragenesis observed within a single mineral deposit. The unique hydrothermal processes provided oxidizing waters to lower parts of the deposit causing the formation of a variety of minerals with increasing depth of the ore body. This provided special conditions for the development of secondary minerals of extreme beauty with respect to form and habit. On January 21, 1893, Mathew Rogers discovered the \"green hill\" and the site started operating in 1907 and closed in 1996 for economic reasons.  Workings include extensive underground openings to a depth of 1,000 meters.\u003c\/span\u003e\u003c\/p\u003e","brand":"Groundstar Minerals","offers":[{"title":"Default Title","offer_id":46425510150373,"sku":"Specimen #100284","price":55.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0649\/8566\/1669\/files\/IMG_0759-Photoroom.jpg?v=1736201378"},{"product_id":"vanadanite-specimen-100285","title":"Vanadinite (Specimen #100285)","description":"\u003cp\u003e\u003cspan lang=\"EN-US\"\u003e\u003cstrong\u003eMineral(s):\u003c\/strong\u003e  Vanadinite\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan lang=\"FR\"\u003eLocation:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan lang=\"EN-US\"\u003e   \u003c\/span\u003e\u003cspan lang=\"FR\"\u003eACF Mine, Mibladen, Aït Oufella Caïdat, Midelt Cercle, Midelt Province, Drâa-Tafilalet Region, Morocco\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan lang=\"EN-US\"\u003e\u003cstrong\u003eSize:\u003c\/strong\u003e   \u003c\/span\u003e\u003cspan lang=\"EN-US\"\u003e5.4 x 2.5 x 2.2 \u003c\/span\u003e\u003cspan lang=\"EN-US\"\u003ecm\u003c\/span\u003e\u003cspan lang=\"EN-US\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan lang=\"EN-US\"\u003e\u003cstrong\u003eDescription:\u003c\/strong\u003e  \u003c\/span\u003eA fantastic vanadinite specimen from Mibladen, easily the source of the world's finest examples of the species.

The geology of the area is rich and complex, featuring metabasalt, felsic rocks, and marble, alongside metallic deposits of iron, copper, nickel, silver, and gold. Mineral collectors are drawn to the site for its diverse specimens, which include magnetite, hematite, pyrite, actinolite, epidote, and its striking garnet specimens. Almandine garnets from this site typically exhibit deep reddish hues and form within the metamorphosed iron-rich skarn zones, often embedded in magnetite-rich rock. In contrast, andradite garnets from Marmoraton are known for their trapezohedral crystal habit, with layered and intergrown formations that range from honey-brown to greenish tones.

It was developed by the Marmoraton Mining Company, a subsidiary of Bethlehem Steel, to extract high-grade magnetic iron ore from Precambrian meta-sedimentary rocks beneath a thick limestone cap. The geology of the area is rich and complex, featuring metabasalt, felsic rocks, and marble, alongside metallic deposits of iron, copper, nickel, silver, and gold.

Almandine garnets from this site typically exhibit deep reddish hues and form within the metamorphosed iron-rich skarn zones, often embedded in magnetite-rich rock.
