Black to translucent green rock

I have a friend who has found a small black rock that looked like it may have been coal. He sat the rock onto his flashlight and it turns bright green. We have been trying to find out what it is and haven't found any description that describes it exact. So I'm hoping you might be able to help.

Thank you

no spark on my mower

i have a small mid engine craftsman mower. It originally had a 11hp briggs and Stratton motor on it, until i blew it. So i had a extra 17hp v-twin briggs and Stratton motor that I put in it. it would start with starter fluid but die because I didn't have the fuel shut off switch on it. But i put a switch on to and i accidentally hooked up the coil shut off wire up to the battery and it was smoking, so i hurried up and unhooked it. so i replaced it and now i have no spark. i just want to know if i need a coil shut off switch or not. and what the spark problem is?

Identifying possible blueberry disease

I purchase four different varieties of 3-4 year old blueberry plants from a local family owned blueberry nursery. I received and planted the plants in early spring following the specific instructions.

I am starting to notice more and more markings on the stems of all four blueberries, and none of the markings are completely identical. I have attached some photos in hopes someone can help me identify if there is a problem and if/what the solution might be.

Gel like substance on apricots on tree

I have a fairly young apricot tree that maybe had 5-10 apricots on it last year, and this year I have many more but they have a gel like substance on the fruit. What is the cause of this and is there anything I can do to save the fruit? I am assuming it is not something good for the fruit!

Hollyhocks changed color.

I had deep purple hollyhocks. There were no other colored hollyhocks in our area. For years they were deep purple. Replanted seeds across the road at my mother ‘s place. They were purple for a couple of years then started changing colors. Frist pinks, then only white now most of them are yellow. No pinks , purple or anything in between. Almost all yellow. What’s happening here?
