Lots of minerals in thie vuggy matrix of altered pegmatite. The specimen features one larger vug that has a rich partial filling of reddish yofortierite with twinned, sixlings of colourless epididymite suspended in the yofrtierite crystals. Throughout the specimen are vugs of bladed albite, aegirine crystals and some other minerals. Many crystal sections of a eudialyte group mineral are embedded in the matrix, as well.
