After waiting 5 min for the last thread to load I figured it’s time for another iteration. My first submission is this quartz crystal who’s terminated was broken off while the conditions were still favorable for growth allowing the crystal to fully heal.

This one had me going for a while but the rest of the piece told just what the mineral was.  At first I was not sure because I had never seen jarosite in this habit but some spots on a different part of the specimen had the same spherical forms but broken and showed it was jarosite.   The jarosite was all over the rest of the piece but I had never seen it like this before.  Field of view is 4mm and it is from the Manila Mine in Cochise Co. Arizona.  I will add the second photo also that shows the broken spheres.

In this photo the broken spheres show the tiny, platy structure typical of the jarosite from this mine.  Field of view here is 5mm.
