Siderite (Whitmore Coll.)

Item Description

Large, rhombohedral siderite crystals are strikingly embedded on both sides of the matrix with smaller siderites on this showy and classic specimen from Mont Saint-Hilaire. The lustrous, partially translucent, two-toned siderites really look like flattened spearpoints! Very uncommon in this style from this renowned locale. Ex Robert Whitmore Collection.
