The zircon crystals, [description: colour, size, habit], sit in a [pegmatite \/ calcite \/ other] matrix measuring approximately [size] overall. Their typically dull, brownish tones contrast with the host rock.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eZircon naturally incorporates small amounts of uranium and thorium into its structure. Over geological time, the radioactive decay damages the crystal lattice, producing the metamict state: lower density, altered optical properties, and often a rough or slightly rounded appearance. Cyrtolite is a good teaching specimen for radiation damage in minerals, and the Bancroft area is a classic Canadian locality for it.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThis is a low-level radioactive specimen, safe for collecting and display. Store it in a closed container, wash hands after handling, and do not grind or powder the material.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eApprox. specimen size: \u003c\/strong\u003e95mm x 45mm x 25mm\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eApprox. specimen weight: \u003c\/strong\u003e100 grams\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eApprox specimen activity on an SE International Ranger EXP:\u003c\/strong\u003e 400 CPM\u003c\/p\u003e","brand":"Rad Man Minerals","offers":[{"title":"Default Title","offer_id":54729143189788,"sku":null,"price":40.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/5524\/1500\/files\/PA180202.jpg?v=1792331984","url":"https:\/\/radmanminerals.com\/products\/cyrtolite-zircon-in-matrix-saranac-property-near-bancroft-ontario","provider":"Rad Man Minerals","version":"1.0","type":"link"}
