Top example of Rhodochrosite from this famous locality. Beautifully intergrown crystals with rich red-brown color and rhombohedral habit. They are complete and have perfect razor sharp shape with strong luster. Some areas are translucent. For references see The Mineralogical Record, 21, 332-333. In superb condition – some very small contacts.
Exceptional first grade Rhodochrosite Mont Saint-Hilaire!
