I know marble is a natural product and there will be imperfections of sort. Can anyone tell me about the surface of marble that has a honed finish, rather than a polished finish? Specifically, my new 18 x18 honed carrara marble tiles have little spots where the surface is dipped in. The tile installer held off on installing them because he wasn't sure if this is within normal limits for honed marble, or if this should be considered a defect. I need to know the answer to that before I call the store that sold it to me, because they are likely to tell me it is normal, whether it is or not. Please share what you know about this! I'm in for a lot a money. Thank you!
