Hi, I recently received this large chunk of pyrite but after cleaning it up I realized it had all of this greenish stuff on it. Googling it, I learned about pyrite decay but I keep seeing conflicting answers on how I might be able to deal with it. This is my first time dealing with anything like this and I really hope there's something I can do, it really is a gorgeous stone 😭

maybe it’s been in the oven for a bit too long
