edit Where to Use

Both granite and quartz are durable choices, and so are good for kitchens that will receive a lot of use and that need to be cleaned quickly and easily. They are both heat resistant, but granite is also porous, and so can be damaged by spilt liquids, and needs resealing every twelve months.

In places with lots of liquid, such as bathrooms, quartz is the preferable choice, as it is non-porous.

edit Maintenance

Granites are heat-resistant and scratch-resistant. Slab granite is porous so it’s susceptible to damage or stains from spilt liquids. It may also be a breeding ground for harmful bacteria. Requires re-sealing every year. No such problem with quartz. Quartz offers a more consistent look because it is engineered while granite is naturally occurring.

edit Cost

The price of both granite and quartz varies depending on availability, manufacturer, the installer, location and so on. typically both cost between $60 and $100 per square foot. Granite is usually more expensive.

edit Health Risks

Some concerns have been expressed about the use of granite in countertops, as it is naturally radioactive and can emit radon. According to a professor at St. Johns University, approximately 5% of granite seems to be of concern. However another study by National Health and Engineering Inc of USA found that 39 granite slabs studied had radiation well below European Union Safety Standards.
