Rows of pits running approximately in 〈100〉 directions on {100} faces of natural diamonds have been observed optically for the first time. The electron micrographs of single‐stage carbon replicas revealed that some of the pits in the row were spiral depressions. It is suggested that these rows of pits are formed by selective dissolution of sub‐boundaries having both edge and screw components.
