Mass allocation of the earth crust mineral crystals in the crystal classes, systems, categories and crystallographic forms has been calculated. The calculation is made on the basis of original data: 1) average density of earth crust mineral crystals equals to 2,8 g/cm3; 2) mass of earth crust is known; 3) the crust of earth is constituted mainly by minerals occurring more often (number of them 3000); 4) main crystallographic forms for the corresponding symmetry classes are known.
