Jesse,
Nice thin sections! Its been a long time, and I was surprised I could still recognize most of the constituent minerals.

Nice to see that even Hawaii has some interesting minerals to offer! As a collector who likes U.S. minerals there are many U.S. states that come to mind when speaking of minerals, e.g. Colorado, Arizona, California, Missouri or Illinois, but Hawaii definitely not among them ;-) So thanks to all here who show us that also those beautiful islands in the Pacific Ocean feature some mineralogical treasures!
