WebWhy are diamonds so brittle? Brittleness is common among ceramics (not just diamonds), which are comprised of covalent and ionic bonds. by contrast, metals are ductile because they readily form atomic disorder called dislocations. The motion of such disorder is the primary mechanism of deformation.
