Granite

Need your help,  Just had Granite (http://tanbrown.org) tops installed in kitchen, there is an L shape that required a seam at the seam it's about a 3 foot piece attached to the L, the problem is the 2 pieces are one lighter one darker, they are the same Colors (http://www.g640.net) just one lighter, the installer said he has been doing this for 11 yr's and (http://maplered.com) he promises that in time the water will dry up and (http://maplered.com) the 2 will match. he said he thinks that when they cut it in the shop they sealed one section and (http://maplered.com) not the other. and (http://maplered.com) the sealed section is dark cause it was a little wet, so he came and (http://maplered.com) sealed the 3 ft section it's still one side darker than the other. he said it's common and (http://maplered.com) that eventually they will dry and (http://maplered.com) match, so is there anyone out there who agrees and (http://maplered.com) give it time or is this not right and (http://maplered.com) should they replace all o0f it, My customer will do what I say so i need someones advice who knows thier Granite (http://tanbrown.org)   John L.
