If it was something at 1 time it isnt much now. They did use that brittle quartz if they couldnt find nothing else but its just to far gone to give a proper I.D. on it now. Its up to you if you wish to keep it. I would use it as a study piece and put it on a shelf for now then after a year or so go back and look at it again. You might see something you missed or you might see it as a totally different thing. My 1st year was tough but after a few since then I cant see why I even picked some up and carried them home. I had a depression in my back yard and used most of my 1st years finds as a filler for it![]()
