A rare, hydrous potassium iron titanium silicate. This heavy, soft and fragile mineral tends to form bladed formations that often radiate from a central point like a star. The name is from the Greek astron meaning "star" and phyllon for "leaf". Found in cavities and fissures in unusual felsic igneous rocks, astrophyllite is associated with feldspar, mica, titanite, zircon, nepheline and aegirine. Common impurities include magnesium, aluminium, calcium, zirconium, niobium and tantalum.
In metaphysical terms, astrophyllite allows for the recognition of self- esteem and limitless possibility, as we are all "stars". It also supports change: as one door closes another opens.
