There are many stone types available to our customers and each have their own look and functionality. Even within the families identified below, the looks can be distinctly different depending on the type of finish specified.



Fissures occur naturally in many stone types. The term “fissure” is used commercially in the stone industry to describe a visible separation along inter-crystalline boundaries. This separation may start and stop within the face of the stone or extend through an edge. A fissure differs from a crack in that it is a naturally occurring feature of the stone. ALL granites contain some degree of fissure. Some contain more than others. Since fissures occur naturally in all granites they are not considered a flaw. Countertops will not be replaced due to the presence of fissures.


Pitting of the countertop surface, particularly in granite, is a commonly seen characteristic of natural stone. Granites are made up of several different minerals, each mineral having a different hardness. Granites contain Quartz, Feldspar, Biotite, Amphibole, ferrous titanium oxides, and other mineral combinations. On the Mohs Scale, diamonds are the hardest mineral with a rating of 10. Quartz and Feldspar have a hardness of 6.5 – 7 and are very durable. Biotite (small, black minerals found through out the slab) on the other hand are very soft (2.5) and can flake easily. All true granites have Biotite in their composition. Because Biotite is relatively soft and flaky, the first few layers can be removed during the polishing process. The pits do not make the granite less durable or otherwise inferior, and do not in themselves qualify a slab for replacement. Pits are common in all granites and should be expected when dealing with natural stone. Countertops will not be replaced due to pitting in the surface of any granite countertop.
