It's not often that you'll find a good quartz point- and when you do, they're made of good solid quartz w/o fractures and inclusions. Yes, I know there are a lot of quartz points out there- and I've found a number of them myself, but what I'm trying to say is that it's a really hard rock to work (pun intended), and if there's a fault line or a variance in it at all, it won't be a successful job. I find a lot of quartz in VA, and I have to think long and hard before I take anything home. I have to look at it hard. And on top of that, it's almost impossible to photo a decent quartz flake- or rough point. They never show the true contour and work along the edge. JMHO. So, I'm looking hard at what you have there, and I lean towards nope. To my eyes, it has too many fault lines- and places where the quartz would be too degraded to be workable. That said, it's too dang hard to see. Keep looking!!
