90 mm Chalcopyrite on Quartz from Kiruna
Kiruna, Norrbotten, Sweden
Size: 38x90x80 mm (273,4 gr.)
The crystals of Chalcopyrite are up to 6 mm and they are laying on a layer of small Quartz crystals. The quartz crystals are dark-purple coated.
The specimen was on display in my father's collection.
I don't know which year it was found, but probably 20-30 years ago.
