Approx. 10 - 15 mm. Extremely popular metaphysically, Clear Quartz is known as the "Master Healer", with its very high vibration, and is the most versatile healing stone among all crystals. Quartz is said to be the most powerful healing stone of the mineral kingdom, able to work on any condition. Clear Quartz is known as the "Stone of Power" and amplifies any energy or intention. Clear Quartz is said to protect against negativity, attune to your higher self, and relieve pain. This extra, high quality Clear Quartz, amplifies the Sacred Geometry energies within these Dodecahedrons, making them ideal for all kinds of spiritual work. The shape of the Dodecahedron is linked to the Higher Self/Divine/All That Is and is a perfect tool to use in meditation and connection with this Source energy. The energy held within the Dodecahedron will raise the holder/users vibration up to meet its own. This allows for a state of connection to Higher Self/Source. Due to its similarity in overall shape to the sphere (much like its dual, the Icosahedron) the energy will be a gentle one, emanating from all sides in equal proportions. This is very helpful when using the Dodecahedron for healing or meditation, as the entire space around you is filled with this energy vibration. Metaphysical aspects of the Dodecahedron Plato described the Dodecahedron as the shape, "... god used for arranging the constellations on the whole heaven". Aristotle added a fifth element, "ether" and postulated that the heavens were made of this element. The Dodecahedron represents the aspects of the Universe (Divine Creation) and is connected with the higher chakras (6th, 7th and above), which hold the energies of meditation, awareness, awakening, higher consciousness and Spiritual Ascension.
