Chocolate dogtooth calcite, small Sandstone avoid touching or inhaling anyLocale: Santa Eulalia, Chihuahua, Mexico Approx size: 22. 5" Approx weight: 45120g Known by the trade name "chocolate dogtooth calcite," this type of calcite from the famed Santa Eulalia mining district grows in hedgehog clusters of sharp dogtooth (scalenohedral) crystals.
