Greenland Minerals, Semenovite-(Ce), Taseq, Ilimaussaq

Here are some excellent examples of the rare mineral Semenovite from the Ilimaussaq Alkaline Complex. The crystals are sort of octahedral-looking with some taking on a more rounded look because of a thicker, outer crystallization. The seminovite is mostly associated with epididymite and natrolite. Rare! Here are some excellent examples.
