As a disclaimer, this isn't the raw specimen (probably obvious) : I got it home and put it on the lap machine right away to create a 'window' to get a better look at what these streaks are in there. Does anyone have an idea what the green and brown streaks inside this quartz are? Is it epidote or am I really off? I've been fascinated with this little piece of quartz for the past few months since I've had it 

I can't believe ultra magnification isn't something that even crossed my mind... I do need to do that and find out. Thanks for putting out  more possibilities of what those could be, Joe.
I will definitely get a better look and hopefully figure it out.
Ultimately, I'm probably going to flatten the back and make it into a cabochon sometime this winter once I've finished my move.

When I found the piece, it was partially buried in the dirt away from the water, and caught my eye when I saw that little green in there. I've been to the same location a couple of times since then but haven't seen anything like it, but I will remain diligent and hope I can find something similar....maybe bigger (one can dream  )

EDIT: I just looked at the link you posted.... wow, yes, very close indeed (and gorgeous) . The green sure looks like the same crystal inclusions. My camera sucks. I need to get a better look in that quartz.
