Quartzite Countertops Guide: The Natural Stone That Does It All
This quartzite countertops guide covers everything fabricators and homeowners need to know.
Quartzite is a natural metamorphic rock formed when sandstone is subjected to extreme heat and pressure deep within the earth, fusing quartz sand grains into an incredibly hard, dense stone. Quartzite combines the flowing, marble-like beauty that homeowners want with the durability and heat resistance that kitchen countertops demand. With a Mohs hardness of 7-8 (harder than granite), quartzite resists scratching, tolerates hot pans, and lasts generations. Installed prices range from $70 to $200+ per square foot.
TL;DR
- Quartzite costs $70-$200+ per square foot installed; average kitchen runs $4,500-$10,000
- Hardness of 7-8 Mohs - harder than granite, much harder than marble
- Heat-resistant: handles hot pans without damage
- Natural stone with marble-like appearance but far greater durability
- Requires sealing annually (it is porous, though less so than marble)
- Popular varieties: Taj Mahal, Super White, Mont Blanc, Fantasy Brown, Sea Pearl
- Not the same as quartz (engineered) - quartzite is 100% natural stone
Quartzite vs. Quartz: Clearing Up the Confusion
The names sound nearly identical, but these are fundamentally different materials:
| Property | Quartzite (Natural) | Quartz (Engineered) |
|---|---|---|
| Composition | 100% natural metamorphic rock | 90-94% ground quartz + resin |
| Formation | Geological (millions of years) | Factory-manufactured |
| Pattern | Unique per slab, natural veining | Consistent, repeatable patterns |
| Heat resistance | Excellent (withstands hot pans) | Poor (resin damages above 300 degrees F) |
| Porosity | Low to moderate (needs sealing) | Non-porous (no sealing) |
| UV resistance | Excellent (outdoor use OK) | Poor (fades in sunlight) |
| Hardness | 7-8 Mohs | 7 Mohs |
| Price | $70-$200+/sq ft | $50-$150/sq ft |

Sealing Requirements
Quartzite is porous, though generally less porous than marble or most granites. Sealing frequency depends on the specific quartzite:
- Dense quartzites (Taj Mahal, Sea Pearl): Seal every 12-18 months
- More porous quartzites (Fantasy Brown, some Super Whites): Seal every 6-12 months
- Apply the water test: Drop water on the surface; if it absorbs within 10 minutes, resealing is needed
The Dolomite Problem
Some stones marketed as quartzite are actually dolomite marble or a quartzite/marble hybrid. True quartzite will not react with acid. To test:
- Place a few drops of diluted muriatic acid or lemon juice on an inconspicuous area
- If it fizzes or bubbles, the stone contains calcite and is marble or dolomite, not true quartzite
- If no reaction occurs, it's true quartzite
This matters because dolomite marble etches (though less than calcite marble) and requires more maintenance. Always verify before recommending quartzite to customers who want acid resistance.

Fabrication Guide for Shops
Cutting Quartzite
Quartzite is one of the hardest materials fabricators work with:
- Blade wear: Quartzite wears diamond blades 30-50% faster than granite; budget for higher tooling costs
- Feed rates: Slower than granite (typically 20-60 inches per minute for bridge saws)
- Water requirements: Higher volume needed to cool blades and control dust
- CNC programming: Account for slower feed rates in production scheduling
Common Fabrication Challenges
| Challenge | Cause | Solution |
|---|---|---|
| Edge chipping | Hard mineral structure | Fresh tooling, reduced feed rate, multiple passes |
| Blade overheating | High friction from hardness | Increase water flow, reduce feed rate |
| Slab breakage | Internal stress lines | Inspect slab carefully, support during cuts |
| Seam visibility | Natural color variation | Book-match from same bundle, CNC seam prep |
| Sink cutout cracking | Stress concentration at corners | Radius all inside corners, avoid sharp angles |
Material Yield
Quartzite yields are similar to granite at 55-75%, but natural fissures and pattern-matching requirements can reduce usable area. AI nesting software helps maximize yield by planning cuts around defect zones while maintaining vein continuity across pieces.
FAQ
Is quartzite better than granite?
Quartzite is harder and often more visually striking than granite, with marble-like flowing patterns. It's better for scratch resistance and pairs heat resistance with a more elegant appearance. However, granite offers more color variety, is generally less expensive, and is easier to fabricate. Neither is objectively "better" - it depends on priorities.
Does quartzite etch like marble?
True quartzite does not etch from acids because it contains no calcite. However, some stones labeled "quartzite" are actually dolomite marble or hybrid stones that do contain calcite and will etch. Always perform an acid test to verify.
How often does quartzite need sealing?
Most quartzites need sealing every 12-18 months. More porous varieties may need it every 6-12 months. Use the water drop test to check: if water absorbs within 10 minutes, the stone needs resealing.
Can quartzite be used outdoors?
Yes. Quartzite is UV-resistant, heat-resistant, and withstands freeze-thaw cycles, making it an excellent outdoor countertop material. Seal it every 6 months for outdoor applications and choose a honed or leathered finish for better grip.
Why is quartzite so expensive?
Quartzite pricing reflects its hardness (which increases fabrication cost and blade wear), limited quarry sources (most comes from specific regions of Brazil), and growing demand as homeowners discover it offers marble's beauty with granite's durability.
What is the most popular quartzite color?
Taj Mahal quartzite is the most popular variety in the US market, prized for its warm white background with soft gold veining. Super White is a close second for homeowners wanting a cleaner, more marble-like aesthetic.
Does quartzite crack easily?
No. Quartzite is one of the strongest natural countertop stones. Cracking is rare and usually results from improper installation (insufficient support), heavy point impacts, or pre-existing fissures in the slab. Natural fissures are common and are not cracks - they're part of the stone's geology.
Is Fantasy Brown a quartzite or marble?
This is debated in the stone industry. Fantasy Brown is technically a dolomitic marble with quartzite characteristics, meaning it's harder than typical marble but softer than true quartzite. It will show mild etching with acid contact. Many suppliers classify it as quartzite, but buyers should expect slightly more maintenance than pure quartzite.
Can I cut on quartzite?
You can cut food directly on quartzite without damaging the stone, but your knives will dull quickly against the 7-8 Mohs surface. Use cutting boards to protect your knives, not the quartzite.
How does quartzite compare to Dekton?
Both are extremely durable. Quartzite is natural stone with unique patterns; Dekton is a manufactured sintered stone with consistent patterns. Dekton is non-porous (no sealing needed) while quartzite requires periodic sealing. Quartzite offers warmer, more natural aesthetics; Dekton offers more industrial and contemporary looks.
