BOULANGERITE, QUARTZ, PYRITE and SPHALERITE |
| Lustrous silver boulangerite needles in a bed of quartz crystals supported on a matrix of pyrite and sphalerite.

These were originally marketed as jamesonite, but X-ray work performed in 1971 showed the species is actually boulangerite. This is an exceptionally large specimen for the occurrence. A specimen label is included.
