The brown patches are probably iron oxide that had settled on the original crystal, then captured beneath a thin secondary layer of clear quartz growth. Two of the termination facets have dull areas of partially exposed phantoms.
The only notable damage to the crystal is a few contact / pressure marks near its base.
