This excellent combination specimen features a sharp, large, 3.5 x 3.5 cm, glassy and translucent, lavender hackmanite crystal set in pearlescent marble and crowned with a rich mass of lustrous, brown winchite. Winchite is an uncommon amphibole group mineral. The hackmanite is a more intense royal purple in daylight and has superb orange fluorescence and also has sulphur-yellow phosphorescence. Outstanding combination material from the Koksha Valley of Afghanistan and the Ed David Collection.\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",563,750,{"id":156,"source_url":157,"license_code":99,"credit_html":158,"title":159,"description":160,"author":103,"original_width":104,"original_height":105},57844,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=24561454","Parent Géry, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=24561454\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Hackmanite, winchite sous UVL 1.JPG","sodalite var. hackmanite, winchite under UVL : Koksha Valley (Kokscha Valley ; Kokcha Valley), Khash &amp; Kuran Wa Munjan Districts, Badakhshan Province (Badakshan Province ; Badahsan Province), Afghanistan",{"id":162,"source_url":163,"license_code":99,"credit_html":164,"title":165,"description":166,"author":103,"original_width":104,"original_height":105},28110,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=24561455","Parent Géry, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=24561455\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Hackmanite, winchite 1.JPG","sodalite var. hackmanite, winchite : Koksha Valley (Kokscha Valley ; Kokcha Valley), Khash &amp; Kuran Wa Munjan Districts, Badakhshan Province (Badakshan Province ; Badahsan Province), Afghanistan",{"id":168,"source_url":169,"license_code":99,"credit_html":170,"title":171,"description":166,"author":103,"original_width":172,"original_height":105},57845,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=24561456","Parent Géry, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=24561456\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Hackmanite, winchite.JPG",3948,{"id":174,"source_url":175,"license_code":99,"credit_html":176,"title":177,"description":166,"author":103,"original_width":104,"original_height":105},28111,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=24561457","Parent Géry, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=24561457\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Hackmanite, winchite 2.JPG",{"id":179,"source_url":180,"license_code":99,"credit_html":181,"title":182,"description":160,"author":103,"original_width":104,"original_height":105},57846,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=24561459","Parent Géry, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=24561459\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Hackmanite, winchite sous UVL 2.JPG",{"id":184,"source_url":185,"license_code":186,"credit_html":187,"title":188,"description":189,"author":190,"original_width":191,"original_height":192},4539,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=85249419","Public domain","Modris Baum, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=85249419\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Cancrinite, Hackmanite-178497.jpg","\u003Ca href=\"https:\u002F\u002Fen.wikipedia.org\u002Fwiki\u002FCancrinite\" class=\"extiw\" title=\"en:Cancrinite\">Cancrinite\u003C\u002Fa>, \u003Ca href=\"https:\u002F\u002Fen.wikipedia.org\u002Fwiki\u002FHackmanite\" class=\"extiw\" title=\"en:Hackmanite\">Hackmanite\u003C\u002Fa>\n\u003Cdl>\u003Cdd>\u003Cdl>\u003Cdd>Locality: Poudrette quarry (De-Mix quarry; Demix quarry; Uni-Mix quarry; Carrière Mont Saint-Hilaire; MSH), Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada\u003C\u002Fdd>\n\u003Cdd>Dimensions: 7 cm x 7 cm x 3 cm\u003C\u002Fdd>\n\u003Cdd>Desciption: Found late 1990s. MOB coll. The violet sodalite (hackmanite) forms a complete orange ring under UV even though part of it looks as if it is coated by a white substance. The black areas are \"biotite\". Note: It has apparently been determined that most, if not all, of the colorless to violet xls formerly deemed cancrinite are actually cancrisilite. As far as I know, the yellowish to orange massive stuff found in sodalite syenite is still cancrinite.\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>","Modris Baum",980,653,[],[195,196],"Hackmanit","Hackmanita",[],{"history":8,"applications":8}]
