Hemimorphite from China. Came with a wrong locality info (Quinglong Mine, Guizhou Province, China), but knowing a lot of Chinese minerals, i knew before that this specimen comes from THE classic Chinese hemimorphite locality of Wenshan:

Good Old Germany always surprises me with its wonderful minerals. Once again, a specimen from a classic Saxon locality. This new specimen is an interesting combination of three (or actually even four) different minerals: It is a quartz crystal, red coloured by hematite (?), surrounded by pale siderite and with some small purple fluorite crystals as special feature. From Ehrenfriedersdorf in Saxony, a city with a long mining history that goes back to the 13th (!!!) century when the digging for tin began ...

Hello Tobi,

Great piece indeed. Am I wrong or you might add the specimen has a phantom and micro pyrite (?) on the siderite the way some Panasqueira specimens have ?

Hi Chris! I did not add the black material on the siderite because i really don't know what it is.

Another quartz crystal, this one is from China and combined with orange garnet crystals:

I hope most of you don't get tired of seeing German minerals classics, so let's go on:

A bunch of "Meißelspat" baryte from famous Clara Mine in Black Forest. Has some small dings, but is nevertheless an interesting and impressive specimen: While most of such barytes are simply grey or brown, this one changes from blue at the bottom to red on the crystal top.
