Seams will always be visible in granite. Their visibility is affected by the granularity, color and pattern of the stone. Seams on a small, uniform grain or dark color will not be as noticeable as they will on a larger variegated grain or lighter color. A dramatic pattern with swaths of color will similarly highlight seams more than a uniform pattern.|
Because granite is usually sold in slabs no more than 10' long, most countertops will require at least one seam. And since granite is sold in rectangular pieces, using seams may also reduce the costs, as in an 'L' shaped corner. Sometimes a seam can be placed at a sink bowl to make it less conspicuous.
