This exceptional specimen features salmon-pink Serandite crystals intergrown with deep green Epidote on a contrasting matrix. The Serandite displays sharp, well-formed crystals with a glassy luster and subtle transparency, while the Epidote presents elongated blades that offer dramatic contrast and mineralogical interest.

Collected from the famed Poudrette Quarry—a globally renowned site for rare and exotic mineral species—this combination piece showcases the aesthetic and mineralogical diversity unique to Mont Saint-Hilaire. The sharp crystal habit and colour contrast make this a standout for cabinet display or advanced systematic collections.
