 Andorite
A stack of thin tabular andorite crystals comprise this thumbnail from the San Jose Mine in Oruro, Bolivia. Andorite is a lead silver antimony sulfosalt and is named after the Hungarian patron Andor von Semsey. Because he gave vast financial assistance to the Mineral Collection of the Hungarian National Museum, Professor Joseph Krenner named andorite and semseyite after him as a mark of his great respect. Andorite, especially Bolivian andorite, is now more properly called andorite-IV to differentiate it from the rarer andorite-VI. Thanks to Mike Keim at Marin Minerals for the specimen and the image!

 Boléite
This intergrown crystal pair of boléite (a lead copper silver oxychloride) comes from the Amelia Mine in the type locality of Boléo, Santa Rosalía, Baja California Sur, Mexico.

A small plastic box of intergrown boulangerite needles from somewhere in Mexico. Ex: James F. Carryer collection. Thanks to Bob Patak at Shadyside Mining for the specimen! |
|
 Bournonite
Bournonite (lead copper antimony sulfide) is often called "cogwheel ore" because of its multiply-twinned radiating crystals. In England it's called endellionite from Endellion in Cornwall (its type locality). This miniature (with manganocalcite and quartz) comes from the Pachapaqui Mine in Bolognesi Province, Ancash, Peru. Bournonite is sometimes used as an ore of lead (42.5%), copper, or antimony. It forms a complete series with seligmannite, where arsenic replaces the antimony, and an incomplete series with soucekite where bismuth replaces the antimony and selenium replaces some of the sulfur. There's often a small amount of tin present as well. Thanks to Rick Green at Uniquely Crystalline for the specimen and the image! | |

Thanks to Tony Nikischer at the Excalibur Mineral Company for the specimen! | |
|
 Cerussite
Cerussite (lead carbonate) is an important lead ore. The crystals, like calcite, are doubly refracting. The fluorescence of the cerussites is interesting - it's a bright yellow but seems to be in either the center or bottom of each crystal rather than uniformly distributed! This one, with its accompanying orange barites and resting on a massive galena layer backed by limonite, comes from Mibladen, Morocco. Thanks to Rick Green at Uniquely Crystalline for the specimen and the image! | |
|
 Cerussite on Duftite

 Galena
This large cabinet specimen has galena on a marcasite and pink dolomite (on the back) matrix from Joplin, Missouri - one of the best localities for this particular mineral association. |
|
Row 32 |
 Galena
This is a thumbnail of massive galena with mint green crusts on two sides, one of which has a couple of millimeter-sized linarite (I think) crystals! The faces of the galena crystals are curved which often means that there's silver as an impurity. |

Thanks to Anthony Jones' auction on eBay for the specimen and the image! | |
|
Row 53 |
 Meneghinite
Meneghinite's a rare lead copper antimony sulfide - this miniature comes from the Kalkan Quarry, Santa Cruz County, California. Most of the literature shows the copper content. It's a member of the aikinite group. |
