A classic and fine cabinet siderite specimen from the Poudrette Quarry at Mt. St-Hilaire. Two large, lustrous, yellowish-brown siderite rhombs are set on matrix covered with small albite crystals. The large rhomb is 5.5 cm on the diagonal. Both rhombs are complete-all-around. These are large siderite crystals for the locale. Ex. James Zigras Collection.
