Fifty-Facet Model of a Diamond-Cubic Crystal

This model uses faces tangent to an inscribed sphere, whose diameter was adjusted to 0.921429 times the vertex sphere so that the ratio between long and short sides of the {001} faces was three i.e. approximately that seen in the experimental images. Which faces are missing? How do the facets compare to those found in nature? For example, how do shapes of the {110} and {111} faces compare? Do experimental face sizes, in comparison to this two-sphere fifty-facet model, reflect the surface energies and/or growth kinetics expected for their respective surface lattice structures? Also, should this model be adjusted to take into account the experimentally-observed biplanarity of the {110} and the "leftover" ~{227} facets, e.g. by creating seventyfour or ninetyeight facet models? Will those "leftover" facets become more "crystallographic" in the process, e.g. might the "leftover facet" bend detail in the closeup image be showing us that {112} faces are more stable than {114}?
