Ussingite, Tugtupite, Sodalite, Polylithionite, Chkalovite - Greenland
*Note: Please make sure to right-click and print (or save) ID card located in the photo gallery for your records* Incredible museum quality specimen of extremely gemmy ussingite plated with bright yellow flourescent polylithionite, tenebrescent sodalite, blue chkalovite, pink tugtupite with tiny spots throughout the ussingite matrix. The gemmiest material found in the complex, this type of ussingite cuts beautiful cabochons. Ussingite seems closely related to sodalite and may even be mistaken for it. The ussingite from the Tunulliarfik area is possibly the best in the complex. Gem quality pieces are found, usually associated with sodalite, tugtupite and polylithionite - making for a striking 4 or 5 color specimen. One of the mysteries of ussingite is its fluorescence – the response seems to vary from bright orange to bright green to none (or very dim).
