Boulangerite from Caspari Mine, Uentrop, Arnsberg, Hochsauerlandkreis, Arnsberg, North Rhine-Westphalia, Germany

Boulangerite specimens from the Caspari Mine, near Arnsberg.

Boulangerite is a lead antimony sulfide mineral and should be considered toxic.

In these pieces it occurs as fine needle-like crystals which are extremely attractive under magnification.

We have a couple of specimens from this locale:

• #1 - 34.1x22.9x9.7MM - excellent under magnification. This specimen is from an old german collection and would benefit from remounting.
• #2 - 32.8x25x8.6MM - This specimen is from an old german collection and would benefit from remounting.
