30012 Natrolite, Aegirine, Mont Saint-Hilaire, La Vallee-du-Richelieu RCM, Monteregie, Quebec, Canada

Comes from a single find made about 20 years ago (~1995). This is a lovely group of 5mm natrolite prisms perched on slender black aegirine crystals. Very aesthetic from any side, and an excellent example of this interesting association.
