An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. The simplest octahedron to make is probably the heptagon based right pyramid. The net for this shape is a regular heptagon with seven identical triangles attached to its edges. If the triangles are folded to meet at a point above the heptagonal base you will have an octahedron.

How many edges does a 3d diamond have?
A 3D diamond, often represented as a regular octahedron, has 12 edges. In geometric terms, a diamond shape can also refer to a rhombus in 2D, but in 3D, the octahedron is the closest representation of a diamond-like form. Each vertex of the octahedron connects to four others, contributing to the total edge count.
