Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada

Dimensions: 18 mm x 17 mm x 12 mm
Largest Crystal Size: 16 mm

This is an example of a distinctive style of twin from this locality. For me, it's a variety of the flanged twins (on {00.1}) seen in calcite and dolomite (though differing here in the presence of the pinacoid). There's a later generation of lustrous rhombohedral crystals.
