MOHS SCALE OF HARDNESS | First State Auctions

The scale we use today is the namesake of German mineralogist, Frederick Mohs, who in the early 1800s, compared the hardness of ten easily accessible minerals. He subsequently charted them, beginning with talc (at the softest rating, 1) and working up to diamond (with a rating of 10, the hardest).

More than the Mohs Scale – Understanding Gem Durability

You may have heard of the Mohs scale, which ranks gem and mineral hardness on a scale of 1 (least hard – talc) to 10 (hardest of all – diamond). But hardness is only one factor in determining gem durability. Gemologists define durability as a gemstone's ability to withstand wear, heat, light, chemicals, and low or high humidity.
