A growing crystal can be understood as a series of polyhedra with faces parallel to planes from a fixed finite set. Such series of polyhedra forms a curve, often broken line, in a vector space of virtual polyhedra. In this paper we apply a modified Minkowski addition to study geometry of a cone of all polyhedra with faces parallel the faces of regular octahedron.
