Sorry this is at the end of the work-week; I had to travel a bit earlier this week.
Diamonds may be a girl's best friend, but graphite crystals are rarer.
More on Sterling Hill:

Nice! I didnt realize that Jersey had such a site.
Add me to your geology ping list please.
How large are those crystals?
I visited Lead Mine road in Raleigh NC to find the mine. I quizzed old timers at a nearby store and heard tales of the civil war and bullets from the mine.
I finally got my trusty topo map and started hunting the mine site on foot. I finally found a pretty good sized hole in the ground and lots of rock with graphite threads.
It apparently was pencil lead.
According to the Web page that these pictures are on, about 1-2 mm.
It appears that there are lots of other graphite morphologies, but pure crystals like this are rare.
You've been added to the list.

Neat! Tried a septarian nodule under a regular black light but no florescence.
