Michael, thank you again so much for sharing your wonderful collection! You always suprise with a lot of things that we don't see that often. Several specimens from Turkey, one of them a quite large gemmy diaspore crystal, a really huge turqoise nugget ... and that bournonite from Bolivia is insane! A superb specimen, congratulations.
Keep up the good work, best regards
Tobi
