We got ours from Ann Sacks but ours is Carrara. They call it a beveled brick. We had them send a sample first to see if it would work. Hope this helps. Here is a link that might be useful:

I do not like this white spot, either. I do not think you are being unreasonable to want to fix it. I think that we are just trying to help you think about other solutions. My first experience with stone was my 2003 kitchen remodel. tumbled marble. I remember looking at the finished backsplash and thinking why didn't my contractor set aside those dark ones that popped up every once in a while. After all, I had three boxes of tile left over. To me, it seemed a no-brainer. I also had no idea there was this much variation. But my contractor did. He knew what the tile looked like and how much variation was there. To him, the dark tiles were not something undesirable, or even something to ask me about. He had more experience, and I had not looked through the tiles to see what they were all like and pulled out the dark ones. Come to think of it, I helped him do tile on the second day. I put extra mastic on the back of the tiles that needed to be set forward a bit. On that day, I did pull out some tiles that were "too dark" for my taste. My expectations were different from Jim's. Now I am doing a second, different kitchen. I have an island that will be topped with 19" porcelain tiles that look like stone. I know from watching HGTV that some people lay tiles like this with no thought to the direction of the streaks of "grain" in the color. I hate that look. SO I am taking off a few hours on tiling day to give my input on the placement of the tiles and cuts. I would not know to do this if I had not seen other tile jobs I did not like, or see the dark tiles on my old backsplash. Since the sealer wears off in time, and since it is a liquid, I bet it has a solvent that will remove it. You may be able to do a "faux" finish on the white spot, then reseal it. It is possible that taking out that tile could hurt your wall and mean that the whole thing has to come down. Try something else first. After Bill Vincent jumps in and gives advice. There is a thread here somewhere about people hiring painters to faux finish outlet covers and other obstructions so that they cannot be recognized and ruin the flow of the backsplash. I would try that before taking out a tile and risking tearing the paper off the drywall underneath. Here is a link that might be useful: Painted outlets

How do you plan to get it smooth? After I did my walkway and was starting on renovating my kitchen, my boss jokingly suggested doing the same thing for my kitchen counters, I thought about it for a minute and dismissed it thinking I would never be able to get it smooth enough. That was my first time working with stone though, and it was very primitive. If I couldn't find a piece to fit where I wanted I would take a bigger piece and drop it on the driveway and it would turn into 3 new pieces.

Touche @ Cinar interiors so you are saying fine sand cant be micro fine sand? really ?Like i said months ago What your doing is repeating stiuff you learned from me right here .Honesty factor into your sales at all? best be honing in and reading up on your outdated scant knowledge of the tile business and industry standards. Like i said you put your foot in your mouth daily I hope dragon also knows better. Sealer may cover up mediocrity but if were being honest here on the upscale hooz instead of selling junk theres a real polishing issue that only gets rectified PROPERLY one way. You all have gone soft. focused on sales when you should be looking at your ethics and bettering the industry. really how many sales or clients have you gotten here??
