Mine scratched from dropping it.  Yes, it hit some little rocks at the bottom of its journey. but it's so slippery!  I am not sure how others have said they have gouged it with keys and knives without a trace of a scratch.  Good luck and good screens to all!!! Stay away from silica!!!  I still wish the OP would post a pic so I could compare screen damage.  how about it?  Try 'macro' mode.
