A cool specimen of lustrous white analcime crystals to 12mm, decorating attractively a microcline base from the famous Mont Saint-Hilaire, Canada. The analcime crystals are complete, sharp and well crystallized with glassy faces. The tabular microcline crystals have a grey color. Black small aegirine needles grow above. Yellowish small crystals of an unidentified mineral are seen too. For references see the 1990 issue of The Mineralogical Record vol. 21, # 4. In good condition – some contacts.

Wonderful!
