Not a stone you usually see.  While there are some specimens made into jewelry, it's a rare mineral that is only of interest to scientists and collectors.  It is a form of Muscovite distinct because of the radiating crystal structure.  Note that astrophyllite has absolutely nothing in common w/ the mineral of the same name mentioned in Rock Hunter's 2015 book about the Roman Catholic Catechism where he says a piece of this mineral can be broken off and it will continue to "live" and grow.
