It's glazed tile. I have no idea where the tile came from other than it
was salvaged from a ship that sunk, and was purchased by my wife's boss
at a firesale price . I am not sure why it cracked.

I may try grouting it, but it's a mottled light yellow/light brown.
Matching will be tough. Thank you.

Our tile store had a sample card showing all the colors of their brand
of grout. I recently read about a tilesetter's tip for blending colors
of grout - mix up a batch of color a, apply, then sprinkle with dry
grout color b. Might work; never tried. You will probably come close
enough with just one color to just make it a bit less obvious. If it is
too fine to fill with grout, buy some face powder and smoosh it in )
