Mohs scale - Wikipedia

WebMohs Hardness Scale, a system founded by Friedrich Mohs in 1812, is a type of chart used to test and contrast the hardness of different minerals. The scale, which can best be described as ordinal rather than linear or logarithmic, provides a rough measure of a mineral’s hardness based on its smooth surface resistance to scratching and abrasion. WebThis is also part of the reason nature's peridot is less robust in the cutting process, shows wear and chipping sooner than a CZ and varies between 6.5 and 7.9 on the Mohs mineralogical hardness scale, while CZ measures a much harder 8.5, as measured by laboratory instruments. WebThere are ten minerals in Mohs scale, talc, gypsum, calcite, fluorite, apatite, feldspar, quartz, topaz, corundum, and for last and hardest, diamond. Because the Mohs scale was made long ago, it is not exactly correct - for example, several minerals are now known to be harder than the diamond. barwa restaurant hobart

All minerals that are orthorhombic, like peridot, are biaxial and are defined by three principal axes: α, β, γ. Refractive index readings of faceted gems contain indices α = 1.653, β = 1.670, and γ = 1.689 with a corresponding biaxial birefringence of 0.036. The refractive index, as well as the specific gravity, slightly vary depending on the iron concentration; a dominant cause of peridot color variation.
