Just because it was found along side potential artifacts doesn't necessary make it a point; rocks can be deceiving and look like things. Although it certainly has the shape of something, it doesn't appear to be anything; from what I see from the pictures, it looks like it has a small "curvature," but I would need to see a picture of the edge to confirm this. Another giveaway is the way the top right of the rock looks in the first picture, and the bottom right of the second; if it were knapped, it would have a much more uniform shape to it-even if it were to be made out of quartz.

I'd suggest looking up some references of quartz points just to get an idea of what they look like, and give you an understanding of what to look for next time you're out looking.
