These pieces are granular crusts rather than single crystals: dense masses of fine intergrown grains, dark grey to near-black, with a bright metallic sparkle across every broken surface where light catches the individual grain faces. The forms are irregular and sculptural — ridged, pitted, and botryoidal, with open cavities and knobbed projections. Scattered brassy grains of associated sulfide minerals sit in the surface of several pieces.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003ePieces range from roughly 1 to 3 inches.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe material is strongly attracted to a magnet — a magnet will cling to a piece and hold there against gravity, including on a narrow edge. Note that the material is not itself magnetized: it will not pick up iron on its own. This is normal for magnetite and worth explaining to a customer who expects otherwise.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eIdentified by field testing rather than laboratory analysis: strong magnetic response and a black streak, both consistent with magnetite and inconsistent with the minerals it is most often confused with.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eNatural and untreated — no dyeing, coating, or stabilizing, as with everything we carry.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eEvery lot is filmed before it ships — what you see in the video is the material that arrives.\u003c\/span\u003e\u003c\/p\u003e","brand":"Crystabelle Fine Minerals","offers":[{"title":"Default Title","offer_id":46020948852819,"sku":null,"price":72.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0636\/5652\/5907\/files\/IMG-5843.heic?v=1787599423","url":"https:\/\/bulk.crystabellefineminerals.com\/products\/magnetite-lot-a","provider":"Crystabelle Fine Minerals","version":"1.0","type":"link"}
