Aegirine


Aegirine is an iron sodium silicate mineral, a member of the pyroxene group (Morimoto et al. 1988). The mineral name alludes to Ægir, the Scandinavian sea-god, since the mineral was first found in Norway.

This is a lustrous black single crystal of aegirine. The interfacial angle approximating 90° distinguishes this crystal from the similar appearing species arfvedsonite. The crystal is doubly terminated; the terminations consists of parallel capillary crystals, much like the end of a brush.
