Au Seeker Posted November 27, 2011 Share Posted November 27, 2011 Kovage,Welcome to the forum!! I added your pictures so it will be easier for others to view.I'm not an expert and others will know more than I do, but it looks like Chert or Flint to me.http://en.wikipedia.org/wiki/ChertA little background on where this rock is from or was found may help with the identification.Skip Quote Link to comment Share on other sites More sharing options...
Red_desert Posted November 27, 2011 Share Posted November 27, 2011 Could be, the 2nd has a spot on it looks like when a rock feels oily. Might be jasper also. Quote Link to comment Share on other sites More sharing options...
