Distinguishing between precious stones and semi-precious stones
Basically, there are various properties that distinguish gemstones from gemstones or semi-precious stones: beauty (color and transparency), rarity and hardness. If the Mohs hardness is greater than 7, it is a gemstone.
Mohs hardness was developed by the mineralogist Friedrich Mohs. Here, minerals are scratched one below the other or with sharp-edged comparative objects. The minerals were ranked by Mohs on a scale of 1 to 10. The softest mineral was assigned a value of 1. The diamond, on the other hand, as the hardest mineral, has received a value of 10.
