The crystals are prismatic, thin, transparent and bright. Some of them are doubly terminated. Due to theirt is color and luster they have a strong contrast with the matrix of Quartz, Albite and Muscovite. The analysis confirms it is Childrenite. Roscherite, also analyzed, is present as very small crystals covering the Childrenite.
