Because Granite is a natural material that comes from the ground it is also on of the most unpredictable in terms of consistency in color, durability and performance over time. Unlike manufactured kitchen countertop materials in which the final product outcome can be predicted and controlled, granite can not be. That is why you will not see a granite warranty on the actual stone unless you are maybe paying double the price of the normal material. You will see warranties on the sealer but not on the actual stone. This is because the final results can be unpredictable.

It is because of these reasons that you want to make sure the company that is fabricating your countertop has proven their quality within the industry. One of the ways to do this with granite is to ask if the fabricator is a member of the Marble Institute of America. The Marble Institute of America is the authoritative source for information and standards of granite workmanship. By being a member, participants are expected to abide by the following Code of Conduct:
