The main cube exhibits sharp edges and smooth, reflective faces with a soft brassy sheen, subtly textured with natural growth markings that enhance its character. Beneath and within the matrix, the edge of a smaller secondary cube is visible—an intriguing detail that hints at the geometric repetition typical of this renowned locality. The pale, granular marl matrix contrasts beautifully with the metallic lustre of the pyrite, making the crystal stand out with impressive clarity. A classic and highly collectible specimen, this piece embodies the precision and aesthetic appeal that Navajún pyrites are celebrated for.\u003c\/h5\u003e\n\u003ch5 data-start=\"34\" data-end=\"380\" style=\"text-align: center;\"\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 approximately 130 million years ago within soft, grey Cretaceous marls—fine-grained sedimentary rocks rich in iron. During this time, sulfur-rich fluids moved through the sediments and reacted with the iron present, forming iron sulfide (FeS₂), known as pyrite.\u003c\/h5\u003e\n\u003ch5 data-start=\"382\" data-end=\"680\" style=\"text-align: center;\"\u003eUnlike many pyrite deposits that form in veins or massive ore bodies, these crystals developed directly within the soft marl layers. The stable, low-pressure environment allowed the crystals to grow slowly and undisturbed, rather than being compressed or distorted by surrounding geological forces.\u003c\/h5\u003e\n\u003ch5 data-start=\"723\" data-end=\"963\" style=\"text-align: center;\"\u003ePyrite naturally crystallises in the cubic (isometric) crystal system, meaning its internal atomic structure favours symmetrical cube shapes. However, what makes Navajún specimens exceptional is the extraordinary precision of these cubes.\u003c\/h5\u003e\n\u003ch5 data-start=\"965\" data-end=\"1387\" style=\"text-align: center;\"\u003eThe soft surrounding rock provided space for uninterrupted growth, while consistent chemical conditions ensured a steady supply of iron and sulfur. With minimal tectonic disturbance and slow crystallisation over time, the crystals were able to develop sharp edges, flat faces, and a striking metallic lustre. This combination of factors results in cubes so perfect they often appear man-made—yet they are entirely natural.\u003c\/h5\u003e\n\u003ch5 data-start=\"1434\" data-end=\"1648\" style=\"text-align: center;\"\u003eThe Navajún deposit is regarded as one of the most important pyrite localities in the world. It consistently produces some of the finest cubic pyrite specimens known, with exceptional clarity, symmetry, and size.\u003c\/h5\u003e\n\u003ch5 data-start=\"1650\" data-end=\"1964\" style=\"text-align: center;\"\u003eFor mineral collectors, it serves as a benchmark locality—often used to represent the ideal form of pyrite. Unlike many deposits mined for industrial purposes, Navajún is worked specifically for high-quality specimens, making it a cornerstone source for collectors ranging from beginners to advanced enthusiasts.\u003c\/h5\u003e\n\u003ch5 data-start=\"1966\" data-end=\"2166\" style=\"text-align: center;\"\u003eThese iconic cubes are more than just “Fool’s Gold”—they are a perfect intersection of chemistry, time, and geological stability, capturing one of nature’s most precise and recognisable crystal forms.\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 rel=\"noopener\" title=\"Authenticity Guarantee here\" href=\"https:\/\/www.forevergems.co.za\/pages\/authenticity-guarantee\" 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 rel=\"noopener\" title=\"Shipping Policy and Rates here\" href=\"https:\/\/www.forevergems.co.za\/policies\/shipping-policy\" 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":46057866985668,"sku":"S603","price":1130.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0273\/1599\/4699\/files\/S603PyriteSpain_1.webp?v=1776420765","url":"https:\/\/www.forevergems.co.za\/products\/pyrite-spain-f603","provider":"ForeverGems_SA","version":"1.0","type":"link"}
