that pc sorta does look like a pestle, does it have any "polish" on roundest end? I mean it doesn't have the classic shape of known pestle types but something to remember the indians didn't produce artifacts in factories with set instructions on manufacturing products. Learn to recognize "polish" and "end use" and you won't have to trust the cloudy opinions of folks that can't see your pcs very well by pictures. Like some cops are trigger happy, there are some "rock" happy folks on here. It may have something to do with insecurities lol im not sure like SVREAPER he suffers from premature berockulation. Why don't you see a doctor about that steve? There are medications that help with that sorta thing.
Again I would classify as ordinary camp rock. Used slightly as pestil and simply discarded. When you find a really good example you will discard it too.
