“A floater octaedric crystals twinned on (111) spinel law from a recent (2019) find.
In isometric native minerals (Cu, Au, Ag, etc) is non common so see so evident octaedric rwins with faces well exposed. Other not misurate faces are present, but probable icosahedron
Acquired from spiriferminerals
In my twinned minerals collection
