{"product_id":"elbaite-tourmaline-double-terminated-2","title":"ELBAITE - Tourmaline   Double Terminated","description":"A long and slender pink double terminated Elbaite Tourmaline crystal, 15.4 cm long, from a recently discovered gem Tourmaline pocket found in the mining district of Coronel Murta in Minas Gerais, Brazil.  This ex-matrix Elbaite crystal is a uniform delicate mix of raspberry-red, rose-pink, and cloudy creamy sugar candy-pink.  The crystal is double terminated, with opposite terminations being totally different.  One is a simple flat pinacoid, with a smooth face with a waxy lustre and is composed partly of gemmy rose-pink Elbaite and translucent, cloudy-cream, sugar candy-pink Elbaite.  The opposite termination is built from a series of stepped terminating small prisms as the single prism resorts to ever narrowing prisms, possibly controlled by a diminishing supply of metal-rich brine within the pegmatite pocket.  These terminations are shallow-sided triclinic pyramids, all with a bright glassy lustre and of cloudy sugar candy-pink culminating in gemmy rose-pink caps.  The prism body is a complete mixture of mainly semi-transparent rose-pink to cranberry Elbaite with included zones of translucent sugar candy-pink.  In cross-section the prism forms a convexly-curved equilateral triangle.  This crystal has undergone four repairs following breaks during tectonic disturbance while in-situ, a common tendency with Tourmaline pockets.  These repairs have been done by experts in this field, rendering them almost invisible.  The prism faces are finely and complexly striated with a glossy silk lustre and texture. A fabulous double terminated Elbaite Tourmaline from Coronel Murta in Brazil.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781132230991,"sku":"CC20802","price":6661.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC20802_cedec751-a40f-49b8-b4ca-4bc4d3fcb372.jpg?v=1783978698","url":"https:\/\/crystalclassics.co.uk\/products\/elbaite-tourmaline-double-terminated-2","provider":"Crystal Classics UK","version":"1.0","type":"link"}
