It is bright silver. Like Cohenite, it is unstable at atmospheric temperatures and pressures and will gradually decompose to kamacite and graphite. The crystal form appears as oriented plates in the matrix of kamacite and taenite. Plate shaped Rhabdites are found in hexahedrites. It is black, with cubic crystal form and octahedral cleavage.
Magnetite is submetallic black with cubic crystal form and octahedral cleavage.
Dont look for red or blue. Gray is the probable color. The common mineral of pencil lead is common as nodules in Iron meteorites and in carbonaceous chondrites. It is black and very soft. This is the same element as graphite.
