{"product_id":"octahedral-pyrite-cluster-peru-1-168-kg","title":"Octahedral Pyrite Cluster - Peru (1.168 kg)","description":"\u003cp\u003eA striking cluster of naturally formed octahedral pyrite crystals from Peru, weighing 1.168 kilograms. The specimen displays dozens of sharply defined octahedral crystals with brilliant metallic luster, interlocking in a dense, sculptural formation. Each crystal face catches light at a different angle, creating a dynamic interplay of gold and bronze tones across the surface.\u003c\/p\u003e\u003cp\u003eOctahedral pyrite forms when iron and sulfur crystallize under specific geological conditions that favor the eight-faced octahedral habit over the more common cubic form. This growth pattern produces crystals with triangular faces that meet at precise angles, a geometry that has fascinated mineralogists and collectors for centuries.\u003c\/p\u003e\u003cp\u003eThis is a substantial cabinet-sized specimen with excellent definition across the cluster. The crystals are well-formed with minimal matrix, allowing the geometric precision of each octahedron to be fully appreciated from every angle.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWeight: 1.168 kg (1,168 g)\u003c\/li\u003e\n\u003cli\u003eOrigin: Peru\u003c\/li\u003e\n\u003cli\u003eMineral: Pyrite (iron sulfide, FeS₂)\u003c\/li\u003e\n\u003cli\u003eCrystal System: Isometric\u003c\/li\u003e\n\u003cli\u003eHabit: Octahedral\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Renato","offers":[{"title":"Default Title","offer_id":52895962399009,"sku":null,"price":175.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0252\/6845\/3410\/files\/pyrite-octahedral-1168g-1907.jpg?v=1782404932","url":"https:\/\/www.crystals.com\/products\/octahedral-pyrite-cluster-peru-1-168-kg","provider":"CRYSTALS.COM","version":"1.0","type":"link"}
