Circa 1812, German mineralogist Frederich Mohs (1773-1839) chose ten (10) commonly available minerals as the basis for his Mohs Scale of Mineral Hardness. Mineral hardness is defined by the Merriam-Webster Dictionary as "the cohesion of the particles on the surface of a mineral as determined by its capacity to scratch another or be itself scratched." Some scientists and historians believe that the minerals selected by Moh were arbitrarily based.
Mohs Hardness Scale
1. Talc (Talcum Powder)
2. Gypsum (Plaster of Paris)
3. Calcite (Limestone and Sea Shells)
4. Fluorite (Fluorine)
5. Apatite (Phosphates, Arsenates and Vanadates)
6. Orthoclase (Feldspar)
7. Quartz (Silicon Dioxide or Silica)
8. Topaz (Emerald and Aquamarine)
9. Corundum (Sapphire and Ruby)
10. Diamond (Carbon, Native Element)
Also note that these minerals can be used in your daily magickal and energy workings.
