{"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":46545389519023,"sku":"CC27373","price":4000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC27373.png?v=1770388177","url":"https:\/\/crystalclassics.com\/products\/rhodizite-londonite","provider":"Crystal Classics","version":"1.0","type":"link"}
