Very beautiful specimen with lots of very glossy golden chalcopyrite crystals, contrasted by colorless, pale blueish gray appearing tiny quartz crystals.

From one of the most wel-known classic German localities.

Much better in nature. The golden chalcopyrite is so glossy, it's hard to gt the reflections out.
