This rare species of hematite is characterized by accumulations of "specular" or mirror-like hematite flakes, creating a metallic or sparkling effect. This freeform slice from the Champion Mine in Marquette County, Michigan - the world's only genuine source of Specularite - has been polished on one side to further enhance the already dazzling luster of this uniquely collectible piece, leaving the other side raw to show the specimen in its natural state.
