Most serpentines are opaque to translucent, light, infusible and susceptible to acids. All are microcrystalline and massive in habit, never being found as single crystals. Luster may be vitreous, greasy or silky. Colors range from white to grey, yellow to green, and brown to black, and are often splotchy or veined.
