Crystal Quartz Platonic Solids Set

Crystal Quartz Platonic Solids Set

This affordable platonic solid set comes without a box or explanatory card and is made from quartz. The set includes one tetrahedron, one hexahedron, one octahedron, one dodecahedron, and isocahedron, all ranging in size from ½" to ¾". The quartz was mined in Brazil and may have some inclusions, though is otherwise clear.

Quartz is a silicon crystal usually occurring in the form of druzy, 6-sided prisms, or massive crystals and it is the second-most abundant mineral on earth. It has been most commonly used for carved art and for jewelry, though their piezoelectric abilities are also highly useful. Its clear form is often referred to as "rock crystal," and ancient philosophers once thought it was a form of supercooled ice. Though this product is the rock crystal form of quartz, quartz also comes in the forms of agate, amethyst, aventurine, carnelian, chalcedony, citrine, jasper, milky quartz, onyx, prasiolite, rose quartz, rutilated quartz, smoky quartz, and tiger's eye.

Rock crystal quartz is an invaluable component of the crystal oscillator, which is invaluable to precise timekeeping devices and solid state electronics. One of the first contexts for this use was as a phonograph pickup. Additionally, due to its triboluminescent properties, quartz crystals were collected and used by the Ute people of Colorado to generate flashes of light in night ceremonies. It is thought that quartz may be the maban stone of Aboriginal Australian lore. In Ireland, it is referred to as "sun stone," possibly because of it's ability to split light into a spectrum.

Rock crystal is, in fact, the traditional material of crystal gazing balls. According to The Book of Talismans, Amulets, and Zodiacal Gems by William Thomas and Kate Pavitt, because of the Moon's rule over the sign of Cancer and powers of intuition, rock crystal/clear quartz is thus a stone well-matched with Cancer.

The five platonic solids are the only flat-faced 3D shapes (polyhedron) which can be composed only of identical sides, each point connecting to the same number of sides. During the early days of geometry, mathematics were considered a matter of philosophy, and perfect forms such as these were considered sacred, hence the name "sacred geometry." These specific five polyhedrons are called "platonic solids" after Plato, who theorized that it each shape was associated with a classical element. These forms are thought to represent the concept of mathematical beauty.

The tetrahedron is composed of four equilateral triangle faces, forming a triangular pyramid. It has six edges and four points. Plato associated it with fire. Astronomer Johannes Kepler associated it with the planet Jupiter. It is also the only platonic solid which is self-dual (you can nest another tetrahedron inside it so that each point of the inner tetrahedron meets the centre of the outer tetrahedron's faces) and is the only platonic solid that isn't centrally symmetric. Tetrahedrons occur naturally in crystal structures.

The hexahedron is composed of six square faces, forming a cube. It has twelve edges and eight points. Plato associated it with the element of earth, and Kepler associated it with the planet Saturn. It can pair with the octahedron to form a dual polyhedra, in which the octahedron is nested inside the hexahedron such that each point of the octahedron meets the centre of a hexahedron face. Hexahedrons occur naturally in crystal structures.

The octahedron is composed of eight equilateral triangle faces, forming a square bipyramid. It has twelve edges and six points. Plato associated it with air, and Kepler associated it with the planet Mercury. It can pair with the hexahedron to form a dual polyhedra, in which the octahedron is nested inside the hexahedron such that each point of the octahedron meets the centre of a hexahedron face. Octahedrons occur naturally in crystal structures.

The dodecahedron is composed of twelve regular pentagonal faces, forming a ball-like shape. It has thirty edges and twenty points. Plato associated it with the heavens, and Kepler associated it with the planet Earth. It can pair with the icosahedron to form a dual polyhedra, in which the dodecahedron is nested inside the icosahedron such that each point of the dodecahedron meets the centre of an icosahedron face. An arrangement of five hexahedrons within a dodecahedron, such that each of their points is matched with a dodecahedron point, forms a polyhedron compound called the "compound of five cubes."

The icosahedron is composed of twenty equilateral triangle faces, forming a ball-like shape. It has thirty edges and twelve points. Plato associated it with the element water, and Kepler associated it with the planet Venus. It can pair with the dodecahedron to form a dual polyhedra, in which the dodecahedron is nested inside the icosahedron such that each point of the dodecahedron meets the centre of an icosahedron face. Many viruses take on the shape of an icosahedron.
