Description

This is a very nice modern classic with tarnished quite well defined and big bornite crystals on matrix. Some quartz crystals present as well as a very small single highly LW-UV fluorescent tabular crystal of a secondary uranium mineral (uranocircite & autunite come to mind, i washed the specimen to be sure that it is no anthropogenic contamination, after rinsing etc it is still there, curious thing). Older material, nowadays no more finds possible.
