Quartzite
Taj Mahal, Sea Pearl, Cristallo and other trade names
A metamorphic stone formed when sandstone recrystallizes under heat and pressure — mostly quartz, which makes it dramatically harder and more acid-resistant than marble. It delivers marble-like veining with close to granite-like toughness.
Why it matters
Quartzite occupies the most confused corner of the slab yard: soft dolomitic marbles are routinely sold as "quartzite" because they look similar and the word sells. Real quartzite will not etch from lemon juice and will scratch glass; mislabeled stone fails both tests. For anyone specifying a hard-working luxury kitchen, this one distinction is worth thousands.
Benefits
- Marble aesthetics with genuine acid and scratch resistance
- Handles daily kitchen chemistry (citrus, wine, vinegar) without etching
- Dense enough that many varieties need minimal sealing
- Works outdoors and in high-traffic flooring where marble would not survive

Performance
Watch-outs
- Rampant mislabeling — dolomitic marble sold as quartzite is the classic slab-yard bait
- Some varieties are more porous than the category's reputation suggests; test the actual slab
- Harder on fabrication: cutting and edging cost more than marble
What to verify
Finish, binder, sourcing, and installation conditions to confirm before specifying.
- Run the tests: lemon-juice etch test and glass-scratch test on a sample of the actual lot
- Porosity of the specific variety (water-drop absorption test)
- That the fabricator has cut quartzite before — inexperience shows at sink cutouts
