It was an early find of tugtupite, ussingite, polylithionite, chkalovite from the cliffs above Tugtup Agtakôrfia. An area of particular note is the large chkalovite crystal fluorescing bright blue under longwave contrasting against the bright orange ussingite\/sodalite, we've not seen this before, very unusual. You'll see the distinct tugtupite veining replacing the chkalovite under shortwave 254nm UV.\u003c\/p\u003e\n\n\u003cp\u003eTugtup Agtakôrfia is a small area right on the water in the Tunulliarfik Fjord. It is the type locality for tugtupite – discovered in 1962 by Sorensen. All of the pink\/red tugtupite has since been mined and all that was left in the vein were some remarkable specimens of sodalite.\u003c\/p\u003e\n\n\u003cp\u003eUssingite is a major mineral found within the complex (of interest to the fluorescent community). It is a fine-grained mineral (similar to quartzite in texture) and ranges in color from white to a deep gem purple. Deeply colored pieces are used for cabochons and can be quite attractive. The fluorescent properties of ussingite remain a mystery. Many pieces do not fluoresce at all (or very dimly), while others fluoresce orange identically to sodalite. A few fluoresce a brilliant green. Tenebrescent ussingite has not yet been found. Most often ussingite is found associated with chkalovite, polylithionite, sodalite and tugtupite and is a good field indicator of the presence of these other minerals.\u003c\/p\u003e","brand":"MinerShop","offers":[{"title":"Default Title","offer_id":52041032302888,"sku":"MSJ0472-102","price":2900.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0714\/4253\/0600\/files\/SW_966b0dba-2653-4a8f-8532-3a106dabe077.png?v=1782764895","url":"https:\/\/www.minershop.com\/products\/ussingite-tugtupite-sodalite-polylithionite-chkalovite-greenland-msj0472-102","provider":"MinerShop","version":"1.0","type":"link"}
