Mohs Hardness Reference Chart - We are so happy to introduce our very own Mohs Hardness Reference Chart, created by our Graphic Artist and our fantastic Consulting team at Healing Crystals. This laminated Mohs Hardness Reference Chart measures 8 ½” x 11” and lets you locate, at a glance, what a Crystal’s hardness is, based on the Mohs scale, a method used to measure how hard a substance is when it is scratched by another substance; in other words, a mineral’s relative resistance to scratching. According to the Mohs scale, substances are listed from 1-10, with 1 (talc) being the softest and 10 (diamond), the hardest.
The front of each Reference Chart lists Crystals, from Abalone to Zoisite, and their corresponding Hardness number. The back of each chart shows Hardness numbers and their corresponding Crystals. What a handy reference chart to have at your fingertips!
