Quartz is engineered; quartzite is natural stone. How they differ on durability, sealing, heat, look and where each belongs.
Quartz is an engineered slab made from crushed quartz and resin; quartzite is a natural metamorphic stone. Quartzite is harder, more heat- and UV-resistant and suitable outdoors, but it must be sealed and true quartzite slabs usually cost more. Quartz needs no sealing and offers consistent patterns. Pick quartz for low maintenance indoors; pick quartzite for a natural marble-like look with more durability than marble, or for outdoor use.
Engineered vs natural
Quartz slabs are manufactured, so color and veining are consistent and predictable. Quartzite forms when sandstone is transformed by heat and pressure, so every slab is unique.
Durability and maintenance
Quartzite is very hard and handles heat well, but it is porous and should be sealed. Quartz is non-porous and never needs sealing, but its resin can scorch under hot pans.
Watch for soft stones sold as quartzite. Ask for a scratch test on glass: true quartzite scratches glass; marble and dolomite do not.
Outdoors and in sun
Quartzite is suitable for outdoor kitchens. Quartz is generally not, because UV can fade the resin.
Cost and look
True quartzite is usually priced above mid-range quartz because of quarrying, fabrication difficulty and slab selection. If you love the look of marble but want low maintenance, a marble-look quartz is often the budget answer — browse our 25 quartz designs to compare.

Frequently asked questions
- Is quartzite the same as quartz?
- No. Quartz is engineered with resin; quartzite is natural stone.
- Which is more durable?
- Quartzite is harder and more heat resistant; quartz is more stain resistant because it isn't porous.
- Does quartzite need sealing?
- Yes. Seal at installation and periodically after, based on a water-drop test.
- Which is better for a Houston kitchen?
- Quartz for low maintenance indoors; quartzite for natural stone character or outdoor kitchens.
