Rather than growing upward into typical cubic or nodular shapes, the pyrite crystals were forced to expand laterally (or radially) between compacted layers of shale, forming thin, circular patterns.\u003c\/p\u003e\n\u003cp\u003eThis pyrite sun measures roughly 4” x 3.5” (10.3 cm x 9.3 cm).\u003c\/p\u003e\n\u003cp\u003eA stand will be included.\u003c\/p\u003e","brand":"Bede Fay: Crystal \u0026 Mineral Collection","offers":[{"title":"Default Title","offer_id":46076119941154,"sku":null,"price":35.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0808\/9554\/1282\/files\/3EB5D7F1-A4D8-4274-B8DE-16DAD6C3CD93.jpg?v=1784749002","url":"https:\/\/www.bedefay.com\/products\/illinois-pyrite-sun-miner-s-dollars","provider":"Bede Fay: Crystal \u0026 Mineral Collection","version":"1.0","type":"link"}
