Platonic Solid Quartz Set

This is a set of 5 platonic solid geometric shapes carved from quartz crystal. These five shapes include a 4 sided = tetrahedron, 6 sided = cube, 8 sides = octahedron, 12 sides = dodecahedron and 20 sides is a icosahedron. Useful tools for sacred geometry. The Platonic solids are prominent in the philosophy of Plato, their namesake. Plato wrote about them in the dialogue Timaeus c.360 B.C. in which he associated each of the four classical elements (earth, air, water, and fire) with a regular solid. Earth was associated with the cube, air with the octahedron, water with the icosahedron, and fire with the tetrahedron. There was intuitive justification for these associations: the heat of fire feels sharp and stabbing (like little tetrahedra). Air is made of the octahedron; its minuscule components are so smooth that one can barely feel it. Water, the icosahedron, flows out of one's hand when picked up, as if it is made of tiny little balls. By contrast, a highly nonspherical solid, the he
