Graphite
For the "Looking close... on Friday!" challenge "pencil points" 😊
Graphite is so wonderful ... from graphite powder to wood encased 'pencils' to sticks of pure graphite, I use it for drawing all the time. I rarely stop to think what an amazing mineral it is - so I looked it up on the Wiki and was surprised!
"Graphite, archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure. It occurs naturally in this form and is the most stable form of carbon under standard conditions. Under high pressures and temperatures it converts to diamond"
