{"product_id":"rhodizite-londonite","title":"RHODIZITE - LONDONITE","description":"An excellent example of an intergrown crystal of Rhodizite-Londonite from the Tetezantsio pegmatites at Andrembeso in Vakinankaratra, Madagascar.  This locality is almost in the dead centre of Madagascar and produces a limited but rare suite of pegmatite minerals.  The species Londonite (caesium beryllium oxide) and its potassium analogue Rhodizite form a continuous solid solution series,   The chemical composition of such crystals from this pegmatite lie typically somewhere along this series, so the term Rhodizite-Londonite is a more accurate name, rather then just one of its end members.  You can judge the large size of the crystal from the specimen's overall dimensions, this being 5.8 x 5.3 x 3.4 cm.  The Rhodizite-Londonite is pale lemon with a translucent outer shell and is perched perfectly for display on a highly naturally etched creamy matrix with a sponge-like texture and porosity.  A superb example of this rare pegmatite species.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781188788559,"sku":"CC27373","price":2961.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC27373_382e49eb-fecf-4dfa-a3cd-1b098f7bb9b6.jpg?v=1783980852","url":"https:\/\/crystalclassics.co.uk\/products\/rhodizite-londonite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
