Quartz is slightly different in that it is not 100 percent natural. Instead, countertops are manufactured using 95 percent ground natural quartz and 5 percent polymer resins.
Quartz is made by humans, so the slabs are more consistent. It comes in a variety of styles, many of which look just like natural stone slabs. White quartz countertops look a lot like marble.
Quartz is strong and resistant to cracks, but not quite as resistant to heat. Quartz countertops can be burned with a hot pan. Quartz is not porous, so it doesn't stain and doesn't need to be sealed.
