The crystals exhibit the geometric clarity of the isometric system, with the pyrochlore-group octahedral habit well-defined even through the metamict alteration that affects most specimens at the atomic scale. Despite metamictization, crystal outlines typically remain sharp and display well. Activity levels are moderate and consistent with the mixed uranium-niobium chemistry of the species.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eA historically significant specimen from the type locality, appropriate for advanced radioactive mineral collections and anyone building a systematic survey of uranium oxide mineralogy.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eApprox. specimen size: 25mm x 13mm x 9mm\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eApprox. specimen weight: 13.50 grams\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eApprox. specimen activity on an SE International Ranger EXP: 26000 CPM\u003c\/p\u003e","brand":"Rad Man Minerals","offers":[{"title":"Default Title","offer_id":54083818914076,"sku":null,"price":230.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/5524\/1500\/files\/P5030088.jpg?v=1777853253","url":"https:\/\/radmanminerals.com\/products\/betafite-crystal-cluster-betafo-district-madagascar","provider":"Rad Man Minerals","version":"1.0","type":"link"}
