Outstanding crystal of Narsarsukite from the famous Mont Saint-Hilaire, Quebec, Canada. Narsarsukite is rare sodium, titatnium, iron silicate. It displays one 9mm crystal nestled on a small matrix. It is very well formed with sharp cubic shape and a strong luster. It has dark olive-green color and some dendritic inclusions. For references see The Mineralogical Record, vol. 21, # 4. In excellent condition – one minor nick. On acrylic base.

Superb Narsarsukite!
