Formula: Ag3Pb2Sb3S8
Sulphosalt, antimony-bearing mineral
Crystal System: Monoclinic
Specific gravity: 6.04
Hardness: 2½ to 3
Streak: Steel-grey
Colour: Grey, steel-grey
Common impurities: Fe,Cu
Environments:
Diaphorite occurs in hydrothermal veins formed at moderate temperatures. Associated minerals include
galena, sphalerite,
miargyrite, pyrargyrite,
pyrite, siderite and
quartz
(Mindat, HOM).
Localities
There are two co-type localities:
Příbram District, Central Bohemian Region, Czech Republic
and
Neue Hoffnung Gottes Mine, Bräunsdorf, Niederwiesa, Mittelsachsen, Saxony, Germany
At the Van Silver Property, Brandywine Creek, Vancouver Mining Division, British Columbia, Canada, diaphorite as
black crystals to 5 mm long occurs most frequently in galena-rich veins, often intergrown
with other sulphide minerals. Some individual crystals of diaphorite are perched on colourless
quartz crystals
(Minrec 31.3.225-226).
