Rhombic Dodecahedron Sacred Geometry Bronze Pendant with Chain


Shipping to United States: Free


This fully 3D pendant is a Rhombic Dodecahedron, a convex polyhedron with 12 rhombic sides. This shape is important in the newly emerging cellular universe theory, which says that the universe is made of gravitational cells, shaped like a Rhombic Dodecahedron. There are actually only three ways by which a volume can be divided into ordered 3D cells (identical units with no gaps between adjacent cells): cubes, truncated octahedra, or rhombic dodecahedra. We immediately eliminate the cube as it is unstable when subjected to the forces involved. That leaves the truncated octahedron and the rhombic dodecahedron. The choice of shape depends entirely on the type of force involved. When the forces of surface-tension are involved then the cell tries to minimize the surface area. When the force involved is that of "negative pressure" then the tendency is to maximize the surface area. Thus, surface tension cells, striving to minimize their surface area, take the shape of truncated octahedra, while negative pressure cells, striving to maximize their surface area, take the shape of rhombic dodecahedra.

This design started life as a 3D model, 3D printed in PLA, a corn-based bioplastic. This was cast using a standard investment casting procedure, then cut in half and polished to make a rubber mold. The rubber mold is used to create wax halves, which are joined together and cast in bronze to create the piece. The pieces are then finished by hand.

This 1.5" x 1" x 1" pendant, weighing 22 grams, is made of ancient bronze, an alloy of 90% copper and 10% tin. It comes with a gunmetal chain, with a hypoallergenic dark and shiny coating that will never tarnish or turn your skin green, in your choice of length. Currently ready to ship, ships within 1 week from our SF Bay Area, CA studios.
