"Bravais's law of cleavage (the precursor to the Bravais-Friedel-Donnay-Harker law) makes a sharp quantitative prediction: the easiest cleavage plane {hkl} has the maximum reticular density (equivalent to maximum interplanar spacing d_{hkl} in the primitive lattice). Combining unit cells from COD with ranked cleavage planes from Mindat allows an immediate, large-scale statistical test across hundreds of minerals, cleanly measuring both the substantial predictive success of reticular density and its known failures where chemical bonding and glide/screw symmetries dominate." . . . "Proposed test with existing data: For a large sample of cleavable minerals with known unit-cell parameters and Bravais lattice centering, compute the reticular density (proportional to interplanar spacing d_{hkl} of the primitive lattice) for low-index planes and compare the rank order of d_{hkl} against the observed primary, secondary, and tertiary cleavage planes {hkl} and DFT surface cleavage energies. Confirm if primary cleavage planes systematically match the largest d_{hkl} (or follow decreasing d_{hkl}); refute where covalent bonding anisotropy or basis motif placement causes cleavage along planes of lower reticular density (e.g., fluorite {111} vs {100} in a primitive versus face-centered lattice)." .
