Quartz isn't the only mineral composed from SiO2. There are approximately 8 other known structures that are made from SiO2. All members of this group, except quartz, are uncommon to very rare on the surface of the earth and are stable only under high temperatures and high pressures or both. These minerals have their own unique structures though they share identical chemistry, therefore the term polymorph that means many forms.Quartz has a completely unique structure. In fact there's another mineral that shares quartz's structure, and it's not even a silicate. It's a rare phosphate named belemnite, AlPO4, that's structural with quartz. Quartz involves corkscrewing silicon tetrahedrons chains. The corkscrew takes 4 tetrahedrons to repeat it, or 3 turns. Each tetrahedron is basically revolved 120 degrees. Along the C axis chain are aligned of the crystal and connected to 2 other chains at every tetrahedron making quartz a real tectosilicate. This structure isn't like the structure of the chain silicates or inosilicates whose silicate tetrahedron chains are not immediately hooked up to one another. The structure of quartz explains plenty of its features. For one, the helix makes 3 turns and this helps produce the trigonal symmetry of quartz. Similarly a helix or corkscrew lacks mirror planes of symmetry as does quartz. The corkscrew structure would also interrupt any cleavage which needs an aircraft of weakness not found in quartz and breakage would end in the curved fracture, concordat that is in quartz There are even some extremely tough to identify crystals of quartz that are twinned with swapping one sixths of the crystal being right handed and then left handed. Quartz profusion on the Earth's surface is fantastic and produces some fantastic varieties that do not even look like the same mineral. A collector has to be up on the many types of quartz and it infrequently embarrasses a collector to have picked up too many example of such a typical mineral. But virtually all collectors concede that you can never actually have enough quartz samples. Metaphysical Properties: Quartz is the strongest, flexible multi-purpose healing stone, particular about self confidence, and healing the injuries of a neglectful or violent adolescence. This stone won't let you wallow in self-pity over that which you cannot change! It amplifies the energy of all of the stones and increases your emotional energy. I call this the poor mans Diamond, because it's so loaded in each way except material value. This stone amplifies requests, wishes and positive visualizations. Keeps you in contact with your religious side, and reminds you that you're a non secular being, having a human experience. All non secular pursuits can be excited and amplified using this stone's energy. It helps you to be receptive to higher steerage. Straightforward to clean, store info or energy in, program or amplify energy and heal with. |
