Prehnite is a member the Phyllosilicates Subclass. Like zeolites, Prehnite can give off water when heated, but can not gain the water back like they can.

Its colour is a pleasant green and is at times quite unique to Prehnite. Some Minerals that can be confused with Prehnite are Gyrolite, Smithsonite and Hemimorphite. Prehnite is harder than all of these and lacks Smithsonite’s unusual luster. Hemimorphite is usually blue and Gyrolite is not as glassy. Its color, luster, associations and crystal habits make it a joy to own.
