The pyrite grows in a botryoidal (rounded, grape-cluster) habit — dense nodular masses of micro-cubic crystals that produce a strong metallic flash under light. The host matrix is a pale cream-to-tan limonite or weathered clay, typical of the sedimentary formations where this type of pyrite forms in Pakistan.\u003c\/p\u003e\n\u003ch3\u003eMineral Composition\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMineral:\u003c\/strong\u003e Iron Pyrite (FeS₂) — iron sulfide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal Habit:\u003c\/strong\u003e Botryoidal nodules with micro-cubic crystal faces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatrix:\u003c\/strong\u003e Limonite (iron hydroxide) or weathered clay\/shale\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLuster:\u003c\/strong\u003e Metallic, brass-yellow to silver-gold depending on angle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness:\u003c\/strong\u003e 6–6.5 on the Mohs scale\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eOrigin\u003c\/h3\u003e\n\u003cp\u003eSourced from notable pyrite localities in \u003cstrong\u003eKhyber Pakhtunkhwa\u003c\/strong\u003e (Abbottabad district) and \u003cstrong\u003eBalochistan\u003c\/strong\u003e, Pakistan.

The specimen is raw and unprocessed — no polishing, coating, or chemical treatment has been applied. Minor surface dust or loose matrix particles are normal and can be gently brushed off with a dry brush.\u003c\/p\u003e\n\u003ch3\u003eCare Instructions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eKeep dry — avoid soaking or prolonged moisture exposure. Water can degrade the clay\/limonite matrix and accelerate surface oxidation on the pyrite.\u003c\/li\u003e\n\u003cli\u003eStore away from high humidity environments.\u003c\/li\u003e\n\u003cli\u003eIf cleaning is needed, use a soft dry brush only.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eQ: Is pyrite on matrix more fragile than a standalone pyrite specimen?\u003c\/h4\u003e\n\u003cp\u003eYes. The clay or limonite matrix is softer than the pyrite itself and can crumble if wet or dropped. Handle the specimen from the matrix base and keep it dry to preserve structural integrity.\u003c\/p\u003e\n\u003ch4\u003eQ: Does iron pyrite tarnish or rust over time?\u003c\/h4\u003e\n\u003cp\u003ePyrite can oxidize slowly when exposed to humidity and air, producing a dull surface or minor rust-colored staining. Storing the specimen in a low-humidity environment significantly slows this process.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the difference between botryoidal pyrite and cubic pyrite?\u003c\/h4\u003e\n\u003cp\u003eCubic pyrite forms distinct geometric cube-shaped crystals, while botryoidal pyrite grows in rounded, nodular masses made up of many tiny interlocking crystals. Both are iron sulfide (FeS₂); the difference is in growth conditions and crystal habit.\u003c\/p\u003e","brand":"Folkmarketgems","offers":[{"title":"Default Title","offer_id":53242780909857,"sku":"PYRI-250","price":350.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0845\/4665\/0401\/files\/pyrite-golden-specimen.webp?v=1786453894","url":"https:\/\/www.folkmarketgems.com\/products\/golden-iron-pyrite-on-matrix-250g-pakistan","provider":"Folkmarketgems","version":"1.0","type":"link"}
