Specimen # 201172
Mineral: Stellerite
Location: Dyer Quarry, Birdsboro, Berks Co., Pennsylvania, USA
Size: 6.3 x 5.5 x 2.0 cm


Balls of beautiful stellerite crystals from the Dyer Quarry.  The crystals are translucent with nice lustre, and in excellent condition. Small white areas on this specimen are laumontite, not damage. This specimen has been reinforced from behind to stabilize it – this is not easily visible and not visible at all except when looking at the back/underside. Collected by Skip Colflesh and Scott Snavely in August, 2014. One commonly sees specimens of “stellerite” offered for sale that are in fact stilbite, but Dyer Quarry specimens have been tested and confirmed by Lance Kearns to be stellerite. From the John S. White Pennsylvania Collection, a beauty!
