Octahedron crystal cubic Ilustración e icono

A simplified illustration depicts a regular octahedron rendered as a faceted crystal belonging to the isometric (cubic) crystal system. The polyhedron has eight equilateral triangular faces meeting at six vertices, with varying blue shading indicating facet orientation and light. In crystallography and mineralogy, this geometric solid represents a common crystal habit and symmetry class, used to demonstrate external morphology and octahedral coordination geometry within cubic lattices. The entity shown is a polyhedral model of crystal form.
