In its purest state, sphalerite's chemical composition is ZnS, and can display a gemmy transparent light tan\/yellow color. This is one of the few minerals that can form crystals ranging anywhere between gemmy and transparent to opaque and metallic-like. Opaque or cloudy sphalerite tends to be most abundant since iron easily replaces zinc in the process of formation. This specimen comes from Missouri.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThis item is 3” x 2” and weighs 12.3 oz.\u003c\/span\u003e\u003c\/p\u003e","brand":"Good Earth Rocks Gallery","offers":[{"title":"Default Title","offer_id":47338699915438,"sku":null,"price":75.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0582\/1700\/5230\/files\/IMG_5595.jpg?v=1767902243","url":"https:\/\/goodearthrocksgallery.com\/products\/orbicular-sphalerite-on-marcasite","provider":"Good Earth Rocks Gallery","version":"1.0","type":"link"}
