The Pyrite Cubes from Navajún were formed during the Mesozoic Era, at the end of the Jurassic Period, approx. 120 million years ago. They originated within the sediments of a large delta that covered the Cameros Sierra. The Pyrite was contemporary to the dinosaurs that lived in the same region, the fossils of many of which have been found near the mine. The matrix material is mostly a very fine-grained sedimentary marlstone (clay and calcite), Although Pyrite is relatively abundant in nature, it is very rare to find single crystals fully finished with the perfection and shine of those from Navajún, making it highly appreciated by collectors all over the world. The mine at Navajún first started to be worked in the 1960s and continues to be produce fine specimens today.\u003c\/span\u003e\u003c\/p\u003e","brand":"DavesRockShop","offers":[{"title":"Default Title","offer_id":46540071698511,"sku":"i-min-2385","price":175.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0638\/5568\/9807\/files\/IMG_7554.jpg?v=1787933775","url":"https:\/\/davesrockshop.com\/products\/pyrite-cube-in-matrix-navajun-spain","provider":"Daves Rock Shop","version":"1.0","type":"link"}
