The Weber-Isis® Light-Rhombus has a total of 13 ribs, and 4 spheres made of high-quality amethyst.

The rhombus contains the geometry of light. When two circles overlap, an intersection is created, which is also called "Vesica Piscis" in Sacred Geometry. Within the vesica Piscis, you can draw a cross. When you connect the four outer points of the cross, you get two equilateral triangles, which together form a rhombus. This cross is the basis of the geometry of light. One finds this form among other things in sacred geometry in the description of the morphogenetic structure of the eye. This geometry also describes many things occurring in living nature, such as the development of the growth of a certain number of leaves of a tree.
