The end cut format preserves a natural exterior surface on one face while revealing the internal mineral structure on the polished cut face, giving a direct view of the texture that defines this classification.\u003c\/p\u003e\n\u003cp\u003eRafsa 005 was recovered in Algeria in 2023 and classified as an angrite, a group so rare that fewer than 100 members are known worldwide. The plutonic subtype is even less common, representing material from deeper within the angrite parent body rather than surface lava flows.\u003c\/p\u003e\n\u003ch2\u003eStructure and features\u003c\/h2\u003e\n\u003cp\u003ePlutonic angrites are defined by their coarse-grained igneous texture, a product of slow cooling at depth. Unlike the finer-grained basaltic angrites that represent surface flows, plutonic angrites show large, well-developed crystals of kirschsteinite (a calcium-iron olivine), augite, and anorthite plagioclase. These minerals are essentially unique to angrites, kirschsteinite is rare in any other geological context.\u003c\/p\u003e\n\u003cp\u003eOn the cut face of this end cut, the coarse crystalline texture is visible, with distinct mineral grains distinguishable under magnification. The natural exterior surface retains the weathering patina from the Algerian desert environment.\u003c\/p\u003e\n\u003ch2\u003eScientific context\u003c\/h2\u003e\n\u003cp\u003eAngrites are one of the oldest and most compositionally extreme achondrite groups. They formed on a parent body that was strongly depleted in volatile elements and highly oxidized relative to most other meteorite parent bodies. Radiometric dating places angrite crystallization ages among the earliest in the solar system, some angrites formed within the first few million years after solar system formation.\u003c\/p\u003e\n\u003cp\u003eThe angrite parent body remains unidentified, but its extreme composition suggests a unique and poorly understood early solar system environment.

A slice is cut through the interior of the stone, showing two cut faces. End cuts typically show more natural surface and less interior area than slices of equivalent weight.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does plutonic angrite mean?\u003c\/strong\u003e Angrite refers to the meteorite group, a rare class of achondrites from a highly oxidized, volatile-depleted parent body. Plutonic means the rock crystallized slowly at depth rather than erupting as lava, resulting in the coarse grain size that distinguishes plutonic angrites from basaltic angrites.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is included?\u003c\/strong\u003e The 0.70g end cut shown, in a display box, with a Treasure Coast Meteorite Co. certificate of authenticity.\u003c\/p\u003e\n\u003ch2\u003eCollector significance\u003c\/h2\u003e\n\u003cp\u003eAngrites as a group represent some of the most scientifically significant and collectibly scarce meteorites available. Fewer than 100 angrites are known, and plutonic angrites are a subset of that already small group. Rafsa 005, classified in 2023, is a recent addition to this exclusive catalog. For collectors building a representative achondrite or differentiated meteorite collection, an angrite is a meaningful and difficult-to-obtain specimen type.\u003c\/p\u003e\n\u003cp\u003eBrowse our \u003ca href=\"\/collections\/angrites\"\u003eAngrites collection\u003c\/a\u003e or explore all \u003ca href=\"\/collections\/stony-meteorites\"\u003eStony Meteorites\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eMeteoritical Bulletin entry: \u003ca href=\"https:\/\/www.lpi.usra.edu\/meteor\/metbull.php?sea=Rafsa+005\u0026amp;sfor=names\" rel=\"noopener\" target=\"_blank\"\u003eRafsa 005\u003c\/a\u003e | Classification: Angrite (plutonic) | Find, Algeria, 2023\u003c\/p\u003e","brand":"Treasure Coast Meteorite Co.","offers":[{"title":"Default Title","offer_id":44806939377711,"sku":"RAFSA-005-0.70G-INDIVIDUAL","price":35.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/9724\/9839\/files\/7690354A-4D64-48B9-ACC4-DA7BEAA9F0B2.jpg?v=1766699283","url":"https:\/\/www.tcmeteorites.com\/products\/rafsa-005-plutonic-angrite-extremely-rare-achondrite-0-70g-w-coa-display-box-copy-copy","provider":"Treasure Coast Meteorite Co.","version":"1.0","type":"link"}
