Taj Mahal is a Brazilian quartzite — a metamorphic rock formed from quartz-rich sandstone under high pressure. The result is a stone that looks visually similar to marble (warm white, subtle gold and grey veining) but performs much closer to granite (Mohs 7 hardness, low porosity, acid-resistant).
Pricing runs $84–$160/sf installed in 2026. Standard-grade Taj Mahal: $84–$110/sf. Select-grade (cleaner field, more even veining): $110–$135/sf. Premium-grade (large slabs, dramatic but balanced veining): $135–$160/sf. Premium grades require special order with a 4–10 week leadtime.
Performance distinguishes Taj Mahal from marble in three meaningful ways. First, hardness — quartzite is Mohs 7 versus marble's Mohs 3-4. This means Taj Mahal resists scratching from cookware, knives, and abrasive cleaners. Second, acid resistance — Taj Mahal does not etch from wine, lemon juice, vinegar, or acidic cleaners. This is the single largest practical difference for daily cooking. Third, low porosity — Taj Mahal stains less readily than marble and re-seals well. The maintenance burden is closer to granite than marble.
The visual trade-off is small but real. Taj Mahal does not have the dramatic veining of Calacatta or the soft haziness of Carrara. The veining tends toward subtle, often gold-toned banding on a warm-white field. For owners who want the visual identity of marble without the maintenance, Taj Mahal is the standard answer.
True quartzite versus "soft quartzite." Some stones marketed as quartzite are actually marble or dolomite. The simple test: a kitchen knife will not scratch true quartzite. If you can scratch the slab with a kitchen knife, the stone is calcite-rich (closer to marble) and will perform like marble, not quartzite. Reputable fabricators perform the scratch test on a sample at no cost.
Edge profiles, slab thicknesses, and installation timing follow the same patterns as Calacatta and Carrara. Quartzite is denser and harder than marble, which adds 1–2 days to fabrication time per slab.
Sealing is recommended at install and every 24–36 months thereafter — a longer interval than marble. Many quartzites can technically skip sealing entirely, but a sealed surface resists oil staining better than an unsealed one over years of use.
Common mistakes. Choosing Taj Mahal because the local stone yard called everything "quartzite" — verify with the scratch test. Expecting the bookmatched drama of Calacatta — quartzite veining is subtler. Skipping the seal — saves $40–$120 in materials but accelerates oil-stain risk by years. Choosing thick slabs (3cm) for islands without confirming the cabinet structure can handle the weight (3cm Taj Mahal weighs 20+ pounds per square foot).
