Strzegom (Striegau), Gmina Strzegom, Swidnica County, Strzegom-Sobotka Massif, Lower Silesian Voivodeship, Poland
A really unique specimen of stilbite features a chocolate brown colliform of detail stilbite. It rests with smaller doubly terminated brown and chatoyant tan crystals over a “matrix” of broken smoky quartz. The areas near the quartz show tiny epidote drusy, so this may (??) account for the unusual coloration. Strzegom is central in a larger area mined as a granite quarry for industrial silica.
