The original fireplace surround (using the word original loosely- I think the 'actual original' was just brick) was a brown tile circa early 70's Brady Bunch era I would guess.
The fireplace screen had little swirly iron branches with acorns and maple leaves - not very beachy.
(note in the picture below the diamond placed tiles in front are not part of the hearth...we were just checking colors... didn't seem to have a better 'before' picture)
We replaced the tile with beachy seaglass and used some of the marble from the foyer to tie it together and break up the field of tiny tiles.
To save some money my clever wife took the original screen apart - removing all the forest-y details.
and gave it some fresh paint (yes..more silver paint. I believe the can is still not yet empty... more on that to come).
