· Here are some of the key physical properties of Jasper: Hardness: Jasper has a hardness of 6.5 to 7 on the Mohs scale, which means that it is relatively hard and can withstand scratching and abrasion. Density: Jasper has a density of around 2.5 to 2.9 g/cm³, which makes it relatively heavy compared to other minerals.
