The main crystal displays exceptional geometric precision with smooth, reflective faces, while a smaller stepped cube perched on top adds unique character and collector appeal. Rich metallic gold tones contrast beautifully with the soft, earthy matrix, highlighting its natural formation environment. Subtle growth marks and surface textures affirm its authenticity, making this a visually captivating and genuine specimen from one of the world’s most iconic pyrite localities.\u003c\/h5\u003e\n\u003ch5 style=\"text-align: center;\" data-end=\"509\" data-start=\"0\"\u003eThe world-famous pyrite crystals from \u003cspan class=\"hover:entity-accent entity-underline inline cursor-pointer align-baseline\"\u003e\u003cspan class=\"whitespace-normal\"\u003eNavajún\u003c\/span\u003e\u003c\/span\u003e formed around 130 million years ago within soft, iron-rich Cretaceous marls. During their formation, sulfur-rich fluids moved through these sediments and reacted with the iron present, allowing iron sulfide (FeS₂), or pyrite, to crystallise directly within the rock. Unlike many pyrite deposits that form in veins or massive ore bodies, these crystals grew in a calm, stable sedimentary environment, free from pressure or distortion.\u003c\/h5\u003e\n\u003ch5 style=\"text-align: center;\" data-end=\"1009\" data-start=\"511\"\u003ePyrite naturally crystallises in the cubic (isometric) system, but what makes Navajún exceptional is the extraordinary precision of its cubes. The soft surrounding marl allowed crystals to grow without interference, while stable chemical conditions and slow crystallisation enabled perfectly even development. With minimal geological disturbance, the crystals retained their sharp edges, flat faces, and highly reflective, mirror-like surfaces—often appearing almost artificial in their perfection.\u003c\/h5\u003e\n\u003ch5 style=\"text-align: center;\" data-end=\"1517\" data-start=\"1011\"\u003eThe Navajún deposit is regarded as one of the most important pyrite localities in the world. It consistently produces high-quality, well-formed cubic crystals, making it a benchmark for collectors and mineral enthusiasts. Unlike many pyrite sources mined for industrial use, this deposit is valued specifically for specimen-grade material. For collectors ranging from beginners to advanced, Navajún pyrite represents a rare combination of natural beauty, geological significance, and textbook crystal form.\u003c\/h5\u003e\n\u003ch5 style=\"text-align: center;\"\u003e \u003c\/h5\u003e\n\u003ch5 style=\"text-align: center;\"\u003e🌍\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eImportant Info Before You Buy\u003c\/strong\u003e\n\u003c\/h5\u003e\n\u003ch5 style=\"text-align: center;\"\u003eWe want your shopping experience with\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eForever Gems\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eto be as smooth and sparkly as possible!\u003cbr\u003eBefore you add to cart, please take a moment to read these quick notes 👇\u003c\/h5\u003e\n\u003ch5 style=\"text-align: center;\"\u003e🛒 \u003cstrong\u003eOnline Availability\u003c\/strong\u003e\n\u003c\/h5\u003e\n\u003ch5 style=\"text-align: center;\"\u003eThis product is currently\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eavailable online only\u003c\/strong\u003e.\u003cbr\u003eWe sometimes have similar pieces in our store, but we can’t guarantee this exact one will be there.\u003cbr\u003e💡\u003cspan\u003e \u003c\/span\u003e\u003cem\u003eIf you’d like to see this specific item in person, just let us know — we’ll happily arrange for it to be available in-store!\u003c\/em\u003e\n\u003c\/h5\u003e\n\u003ch5 style=\"text-align: center;\"\u003e📸 \u003cstrong\u003eAbout Our Product Photos\u003c\/strong\u003e\n\u003c\/h5\u003e\n\u003ch5 style=\"text-align: center;\"\u003eWe take care to show our items as accurately as possible, but small differences in\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003ecolor or scale\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003emay occur depending on lighting or your screen settings.\u003c\/h5\u003e\n\u003ch5 style=\"text-align: center;\"\u003e📏 \u003cstrong\u003eCheck the Description for Size Info\u003c\/strong\u003e\n\u003c\/h5\u003e\n\u003ch5 style=\"text-align: center;\"\u003eEach listing includes detailed size and weight information — please check it out to get the best idea of what to expect.\u003c\/h5\u003e\n\u003ch5 style=\"text-align: center;\"\u003e🪶 \u003cstrong\u003eAuthenticity Guaranteed\u003c\/strong\u003e\n\u003c\/h5\u003e\n\u003ch5 style=\"text-align: center;\"\u003eWe’re proud of our collection and stand behind every piece.\u003cbr\u003eYou can read our full\u003cspan\u003e \u003c\/span\u003e\u003cspan\u003e\u003ca href=\"https:\/\/www.forevergems.co.za\/pages\/authenticity-guarantee\" title=\"Authenticity Guarantee here\" rel=\"noopener\" target=\"_blank\"\u003e\u003cstrong\u003eAuthenticity Guarantee here\u003c\/strong\u003e\u003c\/a\u003e\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eto learn more about how we verify each specimen.\u003c\/h5\u003e\n\u003ch5 style=\"text-align: center;\"\u003e🚚 \u003cstrong\u003eShipping Questions?\u003c\/strong\u003e\n\u003c\/h5\u003e\n\u003ch5 style=\"text-align: center;\"\u003eWe’ve got answers!\u003cbr\u003eFind all the details in our\u003cspan\u003e \u003c\/span\u003e\u003cspan\u003e\u003ca href=\"https:\/\/www.forevergems.co.za\/policies\/shipping-policy\" title=\"Shipping Policy and Rates here\" rel=\"noopener\" target=\"_blank\"\u003e\u003cstrong\u003eShipping Policy and Rates here\u003c\/strong\u003e\u003c\/a\u003e\u003c\/span\u003e.\u003c\/h5\u003e\n\u003ch5 style=\"text-align: center;\"\u003e💎 \u003cstrong\u003eWhat You See Is What You Get\u003c\/strong\u003e\n\u003c\/h5\u003e\n\u003ch5 style=\"text-align: center;\"\u003eThe item pictured is the\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eexact piece\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eyou’ll receive — no surprises, just the real deal.\u003c\/h5\u003e","brand":"ForeverGems_Tuc26","offers":[{"title":"Default Title","offer_id":46057831366852,"sku":"S595","price":850.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0273\/1599\/4699\/files\/S595PyriteSpain_1.webp?v=1776420465","url":"https:\/\/www.forevergems.co.za\/products\/pyrite-spain","provider":"ForeverGems_SA","version":"1.0","type":"link"}
