Hardness & Durability
Origin Region
Found worldwide with notable deposits in Russia, China, USA, South Africa, and Italy
Hardness & Durability
Mohs hardness ranges from 2.5 to 5.5 depending on the specific mineral species and purity; overall low to moderate durability, making it sensitive to scratching and harsh chemicals
