@Micromineral Gorgeous astrophyllite! Those bronze metallic blades with that distinctive submetallic luster are textbook perfect. The way the crystals radiate in those stellate groups is so characteristic of the species. Mont Saint-Hilaire always produces such exceptional specimens of the rare alkaline minerals.
