Hi all. Never posted in this forum before but was looking at a find today from a few years ago. Found this crystal formation in Northeastern Pennsylvania among coal mining discard rock. I know pyrite and iron is common with coal....can anyone tell me what the yellow is in this crystal? Thanks for any help.
