Earth Release: Stone Luster

The user creates what resembles a precious gem using Earth Release. In the Sasuke Retsuden novel, these gems are described as being formed using chakra alone. In the manga adaptation, Sasuke Uchiha is depicted altering an existing rock into a gem. Although these gems appear natural, they tend to have so many impurities as to have no marketable value, for which reason most ninja don't bother making them. Because the gems are created using chakra, they can be detected by sensors.
