TERMINATED AEGIRINE CRYSTALS
An excellent specimen of Terminated Aegirine Crystals. Beautiful shiny black clustered crystals. They appear as a single large crystal but on closer inspection are several growing together. Many terminated crystals and an amazing collection of crystals at one end. An unusual talking piece for the collection. It is rare to find this quality of Aegirine available. A great gift or treat!

Forming impressive crystals that have become classics among collectors. These tall opaque monument like crystals that jut majestically out from their host rocks are simply splendid. Named after the Norse God of the Sea Aegir. Aegirine is difficult to distinguish from its close cousin Augite. Under normal circumstances, the steep pyramids of Aegirine are the only point of differentiation.
