| Title | Stephanite with quartz |
|---|---|
| Description | Stephanite, Ag5SbS4 (silver antimony sulfide), is an uncommon silver bearing mineral. Although not a well known ore of silver, it is never-the-less a locally important ore in some mines. Stephanite typically forms nicely shaped crystals that are tabular to short prismatic. Its crystals can have a pseudohexagonal outline, making them look like crystals of polybasite, a closely related mineral. Stephanite lacks polybasite's rhombic striations on its pinacoidal faces, good cleavage and the red flashes. Here it can be seen with quarz (white). |
