My* mindat paper is published in American Mineralogist! I feel almost like a real scientist. Now I need to beg for views and citations like some kind of Youtube influencer. Yay. pubs.geoscienceworld.org/msa/ammin/ar... * Other co-authors may exist.

So I was given this old trophy that had a rock on it, and turns out it's a piece of "platinum-rich"* ore from the Merensky Reef, South Africa. Some nice visible chromite and sulfides (pentlandite/pyrrhotite?) along with the usual silicate gunk. * Everything is relative.
