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?

Elephant Ear Trunk

Any suggestions welcome.
I bought this plant from an online group. Just recently have gotten into plants. I am wondering what in the world to do with this guy. Currently, it wont fit in a pot. The stem itself is at least 4 foot long and 7-8 inches in diameter. I would like to cut the stem down so that I can plant it in a pot.

Paw Paw Seeds

I was wondering if i could just plant a piece of the fruit in some soil. Would that be able to have them germ? How far down in a gallon pot would you plant the seeds or the fruit, if that is possible?

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.
