A classic specimen of Mt. St-Hilaire combines a group of good sized analcime crystals with trapezohedral faces, well defined and interpenetrating each other. With some sérandite crystals, well defined and showing an excellent bright orange color. It is accompanied by aegirine, green fibrous actinolite and crystals of manganoneptunite with a dark brown color, and probably accompanied by thorian britholite-(Ce) (not perfectly identified). An indispensable classic of mineralogy. We will send analysis to the buyer.
