Reuben, with out a controlled experiment how can you be certain the stone
would have been stopped by a UV filter?  It could also have been shattered
into a zillion pieces, all propelled toward the lens.

In backlit situations, the additional 2 air/glass surfaces will clearly make
themselves known, and under other lighting conditions they can cause
additional flare too (though you might not notice it w/o controlled tests).

My lenses have been UV-less for over 20 years, and they're in great
condition; but then my lenses are all Leitz or Leica with their tough
coatings.  If you have some lesser brands of lenses they might have softer
coatings and some form of protection may be prudent.
