Limestone vs Quartzite

Limestone is a sedimentary stone from Anatolia & Indiana, USA, with 3–4 Mohs hardness and a cost of $8–18 / sq ft. Quartzite is a metamorphic stone from Brazil & Anatolia, rated 7 on the Mohs scale at $15–35 / sq ft. The key differences are in hardness, water absorption (Limestone: 1.1% vs Quartzite: 0.1%), and ideal applications (Limestone: Facade, paving, dimension stone; Quartzite: Countertops, outdoor kitchen, pool).

Limestone has a Mohs hardness of 3–4 and Good — dense grades freeze-thaw performance, with 1.1% water absorption. Quartzite rates 7 on the Mohs scale with Outstanding freeze-thaw rating and 0.1% water absorption. In most cases, the stone with higher Mohs hardness and lower water absorption will perform better in exterior and high-traffic applications.

For kitchen countertops, the ideal stone resists scratching, heat, and acid etching. Limestone (Mohs 3–4) and Quartzite (Mohs 7) each have different strengths. Granite and quartzite are generally the best kitchen countertop stones because they resist etching from acidic foods. Marble and limestone, while beautiful, etch with wine, lemon, and vinegar. Check which of these stones has the higher hardness rating and lower acid sensitivity for your specific pair.

Limestone typically costs $8–18 / sq ft per square foot installed, while Quartzite runs $15–35 / sq ft. Price varies significantly by origin, slab size, finish, and regional supply. Rare vein patterns and book-matched slabs command a premium of 2–5× standard pricing. Get current pricing from SmartStones suppliers for your specific market.

Yes — combining complementary stones in a single project is an effective design strategy. For example, using Limestone for a feature wall or shower walls alongside Quartzite for countertops or flooring creates visual contrast and plays to each stone's strengths. A common pairing in luxury homes: marble for bathroom walls with granite or quartzite countertops and floors.

Limestone has a freeze-thaw rating of "Good — dense grades" with 1.1% water absorption. Quartzite rates "Outstanding" with 0.1% absorption. Lower water absorption and better freeze-thaw rating indicate better outdoor performance in cold climates. Both may perform well in warm climates (FL, TX, AZ) where freeze-thaw is not a factor.
