The Mohs hardness of serpentine is 2,5-3; it a soft mineral. Not scrached by a graphite pen; scratched by fingernail, copper etc.
The serpentine group describes a group of common rock-forming hydrous magnesium iron phyllosilicate ((Mg, Fe)3Si2O5(OH)4) minerals; they may contain minor amounts of other elements including chromium, manganese, cobalt and nickel. In mineralogy and gemology, serpentine may refer to any of 20 varieties belonging to the serpentine group. Owing to admixture, these varieties are not always easy to individualize, and distinctions are not usually made. There are three important mineral polymorphs of serpentine: antigorite, chrysotile and lizardite.
Serpentine is a type of metamorphosed sedimentary rock.

Serpentine is a metamorphic mineral, so it was formed by high heat and great pressure, most often from peridotite.

Rhode Island's State Mineral is "bowenite", an attractive green form of serpentine.
No. The hardness of serpentine is 3-4.5, whereas a hardness of at least 7 is needed to scratch glass.
The Mohs hardness of serpentine is 2,5-3; it a soft mineral. Not scrached by a graphite pen; scratched by fingernail, copper etc.
Some forms of asbestos are serpentine minerals. Therefore asbestos may be present in some serpentine mineral deposits and could them be an exposure issue while crushing serpentine. A mineralogist will be able to determine whether asbestos is present in any given serpentine deposit.

Chrysotile serpentine is a typical mineral with splintery fracture and kyanite is an example of a non-fibrous mineral that has this fracture.
