octahedrons
Diamond-shaped geometric forms
Octahedrons is a plural of octahedron, a three-dimensional shape with eight flat triangular faces.
The regular octahedron—with eight identical equilateral triangles—resembles two pyramids joined at their bases.
It appears in crystallography, dice, and geometric art.
The Greek-derived plural octahedra is also used, especially in technical contexts.
