It's unfortunate that so many people wasted so much time on a post that didn't contain the basic information that we all need in order to help with identifying this stuff.

Thanks to Mr. White for his comments. To me, growth dislocations produce what look like fractures--they even have conchoidal markings on their surfaces. Perhaps "fracture" is an inaccurate ...
