{"product_id":"hydroxyapophyllite-k","title":"HYDROXYAPOPHYLLITE-(K)","description":"The interestingly named Bull Run quarry is near to Conklin in Loudoun County, Virginia, about 170 km southwest of Washington.  It is known for its excellent Hydroxyapophyllite-(K) crystals and has a total of thirty five valid species attributed to the operation.  This fine crystal displays parts of four faces of a cube with a naturally cleaved based which has been overgrown by later stage mineralization.  A smaller, 2.4 x 2.0 x 1.4 cm, Hydroxyapophyllite-(K) crystal emerges from one side.  These crystals have opaque cores and translucent faces and display a most attractive bright pearly lustre.  Minor botryoidal white balls of Prehnite form drusy coating around the lower edges.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781143142735,"sku":"CC21631","price":296.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC21631_d22e494f-c4b4-4a64-89b2-383d7d6c202c.jpg?v=1783979560","url":"https:\/\/crystalclassics.co.uk\/products\/hydroxyapophyllite-k","provider":"Crystal Classics UK","version":"1.0","type":"link"}
