Mohs scale of gemstones, their hardness and valuation

Minerals and gemstones have various properties and characteristics that differentiate them from one another. In turn, these differences have consequences on their value and market price. One of them is hardness. How to measure it? Is there a scale of hardness of minerals? The answer to these two questions is the Mohs scale. This scale determines the relative hardness of minerals, but it is not proportional. And how do you find out the hardness of a mineral? Rubbing it with the minerals of the scale. As for how the value of gemstones is determined, several factors must be considered. You must take this into account to know their value, so we advise you to familiarize yourself with them. One of them is its hardness, but others such as color, brightness, scarcity or symmetry also influence.

How many levels does the Mohs scale have?

The Mohs hardness scale is a classification that orders the hardness of 10 minerals. Its creator is Friedrich Mosh, a German geologist and mineralogist, who created it at the beginning of the nineteenth century. What do you base the scale on to establish the order of hardness of minerals and gemstones? Basically, in the ability they have to scratch and be scratched. Its order is ascending, with the softest mineral (talc) being in place number 1 on Mosh’s table. The number 10, therefore, is occupied by the hardest mineral (the diamond). Likewise, with this scale it is possible to measure the hardness of gemstones.
