It often colors many of these rocks to a green color and most rocks that have a green color probably have serpentine in some amount. Serpentine is actually a general name applied to several members of a polymorphic group. Chemical formula: Mg3(OH)4(Si3O5); Hardness: 3 - 4.5; Color: olive green, yellow or golden, brown, or black. 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 or 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. (The above information is provided solely for informational purpose.
