Minerals are identified based on a variety of physical properties. Most notable among these are luster, hardness, streak, cleavage, crystal habit, and color. This kit provides 12 specimens that exemplify one or more of these properties. Students of earth science will be able to explore the rhombic cleavage of calcite, compare the hardness of quartz and graphite, study pyrite's metallic luster, and much more. This kit contains 12 numbered specimens and a specimen key.
