It's dimorphous with tetragonal stolzite. Ex: Cooke Collection and William Pinch. Note: I have recently been informed by an Australian Broken Hill mimeral collector that this is probably stolzite instead of raspite. Thanks to Tom & Vicki Loomis at Dakota Matrix Minerals for the specimen and the images! | | |
|

|
Row 74 |
Semseyite
Semseyite's a rare lead antimony sulfosalt 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 semseyite and andorite after him as a mark of his great respect. This miniature of even rarer tabular semseyite crystals (and calcite spherules on the back) on matrix is from the Herja Mine, Baia Mare, Maramures, Romania. I'm not sure what the matrix is - they're rhombohedral with strongly-curved faces and appear to be coated with something metallic (on a few crystals, the coating is thin enough that it becomes brown and merely lustrous). Semseyite's the end member of a small group of related lead sulfosalts; the members (semseyite, rayite (a semseyite subgroup where silver and thallium replace a small amount of the lead), heteromorphite, plagionite, fülöppite) differ in composition by the amount of sheet galena in their structures with semseyite having the most and fülöppite the least. Thanks to Darrel Merke's auction on eBay for the specimen!
Thanks also to Ildikó Vég for the Andor von Semsey information! |
|
Shannonite

|
Teallite
Teallite's a lead thiostannite (PbSnS2) - this miniature comes from the Carguaicollo (Karguai Khoyo) Mine, Quijarro Province, Potosi Department, Bolivia, the primary source. Teallite should be kept in a dry environment - a damp specimen will decompose into fine-grained galena, colloidal tin oxide ("wood tin"), and hydrogen sulfide. It forms an incomplete series with herzenbergite, tin sulfide.. Thanks to Tom & Vicki Loomis at Dakota Matrix Minerals for the specimen! Thanks also to Fred Barnard for the locale correction and information and teallite storage warning! |

There's also a green duftite (type locality, also) druse on the miniature matrix. According to one reference, tsumcorite forms an incomplete series with mawbyite where the iron predominates over the zinc. Another reference states that tsumcorite forms two complete series; one with thometzekite, where copper replaces the zinc, and another with helmutwinklerite where zinc totally replaces the iron. Thanks to Rick Kennedy's auction on eBay for the specimen! | |
|
Tsumcorite
A much brighter small thumbnail of tsumcorite crisscrossed with duftite veins from the type locality of the Tsumeb (Tsumcorp) Mine. Ex: Gilbert Gauthier (2004) Thanks to Michael Cline's auction on eBay for the specimen and the image! | |

Vanadinite
There's enough vanadinite in the U.S. that it was once considered an ore even though it's only 11% vanadium. Vanadinite, mimetite, and pyromorphite are all chemically closely related - they're (respectively) lead chlorovanadate, lead chloroarsenate, and lead chlorophosphate. This miniature's probably from Arizona. |

It's still an impressive miniature - these haven't been on the market for decades! Thanks to auction on eBay for the specimen! | |
|
Row 82 |
Vanadinite, var. Endlichite Endlichite isn't really a proper mineral - it's an arsenic-rich vanadinite; but it's color and habit are distinctive enough from vanadinite and mimetite that it's often listed separately.
