Platonic Solids Crystal Set
Platonic Solids are shapes which form part of Sacred Geometry. They were first catalogued by the ancient philosopher, Plato (hence their name), although evidence of these most magical of shapes has been found around the world for in excess of 1,000 years prior to Plato's documentation.
They are made up of the 'Five Convex Regular Polyhedra': hexahedron (cube), octahedron (double inverted pyramid), tetrahedron (pyramid), Icosohedron and dodecahedron. The names are derived from the number of sides each shape has: 4, 6, 8, 12, and 20 respectively.
The first four shapes correspond with the elements: earth (hexahedron), air (octahedron), fire (tetrahedron) and water (Icosohedron), with the fifth, dodecahedron, representing heaven, ether or the Universe.
The set also contains 7 shapes in total: the 5 above platonic solids, a sphere and a merkaba (formed from two intercepting tetrahedrons).
A meditation presentation is available describing the source of the Premapranahuti symbol within these sacred geometric shapes here.
