Honestly, we can not say for sure which product will be best for you and your family. That is why we take the time to educate our customers on the pros and cons of each stone. They are all solid choices and aesthetically different from one to the other.
Here is a brief summary on each one:
QUARTZ:
For the most part Quartz is a fool proof product that will not stain. It has a factory warranty. It is not completely heat proof as the advertising claims. It can crack with thermal shock. We always recommend using a trivet or heat pad. Quartz can also chip, but chips are repairable.
QUARTZITE:
Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Quartzite has the look of a marble but it will not react to acidic food like a typical marble would. We recommend using a 15 year sealer. Beware of suppliers that label their stones as quartzite. You should always test the sample for hardness and sensitivity to acid.
