Granite, Quartz and Quartzite Side by Side

Three materials dominate the showroom floor and two of them have confusingly similar names. The material notes at countertop installers redding aedreams set them next to each other, because a Redding countertop buyer is usually choosing on appearance and paying for properties nobody explained.
Granite Is Quarried Rock

Granite comes out of the ground as a slab and is cut, polished and sealed. It is hard, it takes heat without complaint, and no two pieces match, which is either the appeal or the problem depending on the buyer. It is porous to varying degrees, so it wants an impregnating sealer at installation and again periodically. A honed finish shows marks more readily than a polished one.
Quartz Is Manufactured

Quartz is crushed mineral bound in resin and pigment, produced in consistent batches. That consistency is the selling point: what you see in the sample is what arrives. It is non porous, so it needs no sealing at all, and it resists staining better than most stone. The trade off is heat. Resin scorches, so a pan straight off the burner can leave a permanent mark that no amount of polishing removes.
Quartzite Is Neither
Despite the name, quartzite is a natural rock and has nothing to do with engineered quartz. It is typically harder than granite, often dramatically veined, and frequently more expensive to fabricate because it is tough on tooling. Some material sold as quartzite is actually softer marble or dolomite, and the difference shows up as etching around a lemon rather than in the showroom.
The Ones People Overlook
Butcher block is warm, cheap and repairable, and it demands oiling and a tolerance for water near a sink. Soapstone is soft, ages to a deep grey and takes scratches you sand out. Solid surface can be joined invisibly and repaired in place but scratches and scorches. Porcelain is thin, extremely hard and unforgiving to install. Laminate is none of these things and is a perfectly sensible choice on a rental.
Match the Material to the Household
A kitchen that cooks heavily and sets pans down without thinking is better served by granite. A household that wants a uniform pale surface with no maintenance conversation should look at quartz. Somebody who wants a slab that looks like nothing else in town, and is willing to be careful, is buying quartzite. All three will outlast the cabinets underneath them.
