Hi There,

Thank you for your question.

To answer your question, the Carrara Marble materials do not come as sealed directly from the manufacturer. Sealing (just like grouting) would be done right at the job site, at the time of installation. Some of our customers prefer not to seal them, that is why, these materials never come as sealed from the manufacturer. You could locate the natural stone sealers at any home improvement store, such as Lowes or Home Depot, as they have a dedicated section for them.

As far as choices: These Carrara White Marble mosaic tiles come either in Polished (shiny / glossy ) or Honed (matte / non-shiny) finishes. So if you may like the shiny look with the 2" X 4" Brick Mosaic Tile, it is available for purchase at the below link:
