Granite and quartz are two of the most popular choices for surfaces such as floors, walls and kitchen and bathroom counters in the home. Granite is a natural product and available in many unique colors and patterns. It is also heat and scratch resistance making them best suitable for outdoors. Quartz is man-made, non-porous giving it a more consistent appearance. Granites are also more expensive than quartz.

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.
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.
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.
Quartz countertops are made from a combination of crushed quartz, a hard mineral that forms in clusters, and resin, generally in a 93% to 7% ratio. Quartz is produced in many colors and patterns, depending on the colorant and how coarsely the quartz is crushed.
Granite countertops are made from granite, a natural stone composed of quartz, feldspar, and mica. Granite is mined in large blocks that are then cut into slabs.
