Title: Help identify what's inside this rock
Post by: Skep on 05/03/2015 01:06:14

My father and I were breaking open rocks in a creek bed around 40 years ago when we came across this rock.  The rock broke into 4 pieces but he glued the pieces back together.  I've hung onto it all these years and have wondered exactly what it is.  If anyone could shed some light on the subject I would greatly appreciate it.
