The arsenopyrite displays sharply angular, blocky crystal forms with a subdued silver-gray metallic luster, distinct geometric faces, and fine surface textures. Smaller metallic crystals are scattered throughout the specimen, contrasting with a bright white to translucent crystalline matrix. Slender, transparent to milky quartz crystals emerge between the metallic minerals, adding texture and visual contrast to the arrangement.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eArsenopyrite is an iron arsenic sulfide mineral commonly found in hydrothermal ore deposits alongside sulfide minerals such as sphalerite, galena, and pyrite. The Parral mining district of Chihuahua, Mexico, has a long history of silver and base-metal mining and is known for complex mineral associations formed through hydrothermal activity. This vintage-labeled specimen illustrates the contrasting crystal habits and textures characteristic of these mineral-rich deposits.\u003c\/span\u003e\u003c\/p\u003e","brand":"The Crystalary","offers":[{"title":"Default Title","offer_id":67933540745347,"sku":"barrydwr5-2of2-509","price":49.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0390\/4634\/8931\/files\/IMG_3560.jpg?v=1792268420","url":"https:\/\/www.thecrystalary.com\/products\/thunder-egg-agate-sawed-and-polished-oregon-usa-copy","provider":"The Crystalary","version":"1.0","type":"link"}
