{"product_id":"glowing-crystal-geode","title":"Glowing Crystal Geode","description":"Create your own crystal geode - a round rock containing a crystal-filled cavity. First, cast a plaster geode shell in the mold and then fill it with a crystal-growing alum salt solution. The crystal solution contains an ultraviolet-luminous pigment that gets incorporated into the crystals as they form, resulting in a geode that glows in ultraviolet light. An ultraviolet flashlight with holder, as well as a display stand for the geode, are included. Display your beautiful specimen day and night! Learn about how crystals form and why the pigment glows under ultraviolet light.","brand":"THAMES AND KOSMOS","offers":[{"title":"Default Title","offer_id":39398611550417,"sku":"THK550022","price":19.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0506\/2538\/0562\/products\/Glowing_Crystal_Geode.jpg?v=1617494216","url":"https:\/\/www.adventurehobbiesandtoys.com\/products\/glowing-crystal-geode","provider":"Adventure Hobbies \u0026 Toys","version":"1.0","type":"link"}
