Often used as the first step in the creation of beautiful gemstones, cleavage is the tendency of crystalline minerals to fracture along structural planes. These planes of comparative weakness are a result of the regular arrangement of atoms in the crystal, which create repeating surfaces that are apparent when the mineral is subjected to forces such as a sharp impact. Calcite, while not as exciting as a diamond, has the unique trait of having perfect cleavage planes in three directions, forming rhombehedrons. Each kit contains 12 pieces of calcite and six chisels. Each calcite sample is large enough to allow each student to cleave the mineral several times. Hammer and eye protection not included.
