Delusive, sneaky, deceptive, uncertain ... What makes sphalerite deserved such adjectives? For a very long time, geologists couldn’t identify this mineral. Finally, the study confirmed that it is a zinc ore. As a result of rubbing sphalerite against a porcelain plate, gives off the scent of hydrogen sulfide. Sphalerite is also the source of silver, which, especially in the past, there was no shortage in Olkusz mines (Olkusz ores was used for making first Piast silver coin).
Presented specimen is unique on the global scale, it have three polished surfaces and it comes from the area of occurrence holomorphic zinc and lead ores. It was excavated in the Pomorzany mine.
