This piece is a true mineralogical oddity featuring both dimorphs of this chemistry on the same specimen. My eyes popped out of my head when i saw it, as it is only the second such really fine example of this combination I have seen (from the same pocket, actually, though the first one was brought to me several months before the show). I was told, and had long thought, that the much rarer pentagonite occurs under quite different conditions from cavansite, so that they never form together in the same vug. Certainly, I have never SEEN them occur together on the same specimen. Well, these not only formed in the same vug but literally on top of each other, and more than that seemingly INTERGROWN ?!?!?! I think it is both an aesthetically choice and scientifically important specimen.\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",{"id":369,"source_url":370,"license_code":371,"credit_html":372,"title":373,"description":374,"author":375,"original_width":376,"original_height":377},73164,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=151839391","CC BY-SA 4.0","Julio nerd da química, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=151839391\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Cavansita e Pentagonita.jpg","Cavansita e pentagonita, dois polimorfos do composto mineral à base de vanadila de fórmula CaVOSi4O10.","Julio nerd da química",3072,2569,[379,385],{"id":380,"url":381,"label":382,"formula":383,"spacegroup":384,"year":130},10552,"\u002Fcif\u002F10552.cif","Ishida 2009","Ca V Si4 O15 H8","C c m 21",{"id":386,"url":387,"label":388,"formula":389,"spacegroup":384,"year":27},10553,"\u002Fcif\u002F10553.cif","Evans 1973","Si4 Ca V O15 H8",[391],"IMA1971-039",[393,397,401,406,410,413,417,420,424,428,431,434,438,442],{"lang":394,"names":395},"bg",[396],"Пентагонит",{"lang":398,"names":399},"ca",[400],"pentagonita",{"lang":402,"names":403},"de",[404,405],"IMA 1971-039","Pentagonit",{"lang":407,"names":408},"es",[409],"Pentagonita",{"lang":411,"names":412},"eu",[409],{"lang":414,"names":415},"fr",[416],"pentagonite",{"lang":418,"names":419},"it",[7],{"lang":421,"names":422},"ja",[423],"ペンタゴン石",{"lang":425,"names":426},"nl",[427],"pentagoniet",{"lang":429,"names":430},"pl",[405],{"lang":432,"names":433},"ru",[396],{"lang":435,"names":436},"ta",[437],"பெண்டகோனைட்டு",{"lang":439,"names":440},"uk",[441],"Пентагоніт",{"lang":443,"names":444},"zh",[445],"五角石","Q1070745",{"history":11,"applications":11}]
