Occasionally this graphite, which is made of the element carbon, is put under such intense pressure (likely due to hypervelocity collisions of its parent asteroid with other asteroids) that microscopic faulted and twinned cubic diamonds are formed. These extraterrestrial diamonds are known as \"lonsdaleite\". \u003c\/div\u003e\n\u003cdiv\u003e\n\u003cbr\u003eThe Ureilite meteorites are considered to be \"primitive achondrites\". This is in reference to their having some characteristics similar to the more evolved and differentiated achondrites, while also displaying some characteristics of less evolved recrystallized chondrites. In this way, they are \"primitive\". They are closer to achondrites (lacking chondrules) than to chondrites, but they have not quite evolved from their chondritic precursors into fully fledged achondrites.\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eWhat you get:  \u003c\/strong\u003e7.39\u003cstrong\u003e \u003c\/strong\u003egram end piece of NWA 5725  Ureilite meteorite specimen as shown, membrane storage\/display box, and signed Certificate of Authenticity.\u003c\/div\u003e\n\u003cdiv\u003eWe offer a 100% no questions asked 30 day return policy.  \u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eSEE OFFICIAL METEORITICAL SOCIETY ENTRY BELOW\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003ch1 style=\"text-align: center;\"\u003eNorthwest Africa 5725\u003c\/h1\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv class=\"alert\"\u003e\n\u003cp\u003e\u003cstrong\u003eStatus:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eOfficial\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"container mb-4\"\u003e\n\u003ctable class=\"text-table th-left\"\u003e\n\u003ctbody\u003e\n\u003ctr class=\"row\"\u003e\n\u003cth class=\"col-12 col-md-3 col-lg-2\"\u003eBasic information\u003c\/th\u003e\n\u003ctd class=\"col-12 col-md-9 col-lg-10\"\u003e\n\u003cstrong\u003eName:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eNorthwest Africa 5725 This is an OFFICIAL meteorite name.\u003cbr\u003e\u003cstrong\u003eAbbreviation:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eNWA 5725\u003cbr\u003e\u003cstrong\u003eObserved fall:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eNo\u003cbr\u003e\u003cstrong\u003eYear found:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e2008\u003cbr\u003e\u003cstrong\u003eCountry:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eMorocco\u003cbr\u003e\u003cstrong\u003eMass:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e37.1 g\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"row\"\u003e\n\u003cth class=\"col-12 col-md-3 col-lg-2\"\u003eClassification history:\u003c\/th\u003e\n\u003ctd class=\"col-12 col-md-9 col-lg-10\"\u003e\n\u003cstrong\u003eMeteoritical Bulletin,\u003cspan\u003e \u003c\/span\u003e\u003ca title=\"Meteoritical Bulletin, no. 100, MAPS 49, E1-E101 (2014)\" href=\"https:\/\/www.lpi.usra.edu\/meteor\/docs\/mb100.pdf\"\u003eMB 100\u003c\/a\u003e\u003cspan\u003e \u003c\/span\u003e(2012):\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eUreilite\u003cbr\u003e\u003cstrong\u003eRecommended:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eUreilite\u003cbr\u003e\u003cbr\u003eThis is 1 of 724 approved meteorites classified as Ureilite.   \u003cbr\u003e\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"row\"\u003e\n\u003cth class=\"col-12 col-md-3 col-lg-2\"\u003eComments:\u003c\/th\u003e\n\u003ctd class=\"col-12 col-md-9 col-lg-10\"\u003eApproved 28 Aug 2011\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"row\"\u003e\n\u003cth class=\"col-12 col-md-3 col-lg-2\"\u003eData from:\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/www.lpi.usra.edu\/meteor\/docs\/mb100.pdf\"\u003eMB100\u003c\/a\u003e\u003cbr\u003eTable 1 Line 1276:\u003c\/th\u003e\n\u003ctd class=\"col-12 col-md-9 col-lg-10\"\u003e\n\u003cstrong\u003ePlace of purchase:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eErfoud\u003cbr\u003e\u003cstrong\u003eDate:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e2008\u003cbr\u003e\u003cstrong\u003eMass (g):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e37.1\u003cbr\u003e\u003cstrong\u003ePieces:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e1\u003cbr\u003e\u003cstrong\u003eClass:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eUreilite\u003cbr\u003e\u003cstrong\u003eShock stage:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003emedium\u003cbr\u003e\u003cstrong\u003eWeathering grade:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003elow\u003cbr\u003e\u003cstrong\u003eFayalite (mol%):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e26.6 (core)\u003cbr\u003e\u003cstrong\u003eFerrosilite (mol%):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e22.1 (core)\u003cbr\u003e\u003cstrong\u003eWollastonite (mol%):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e0.7\u003cbr\u003e\u003cstrong\u003eClassifier:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eT.
