Quartzite slab - 3CM natural metamorphic stone
Calacatta Black Quartzite 3CM Quartzite
Calacatta Black Quartzite 3CM is a natural quartzite slab from ST Stones. Quartzite is a metamorphic stone (originally sandstone, transformed under heat and pressure over geologic time) - typically harder than granite, with the marble-like aesthetic many homeowners want without marble's softness. This slab is 3CM thick (about 1-1/4 inch). Slab dimensions vary by quarry - typically 110-126 inches long and 55-78 inches tall (roughly 55-75 sqft per slab).

Quartzite is one of the strongest natural countertop options for Palm Beach County. It's a metamorphic stone (sandstone transformed under heat and pressure), harder than granite, scratch-resistant, and heat-resistant. Calacatta Black Quartzite 3CM is slightly porous like all quartzites and should be sealed at installation and resealed every 1-2 years to keep the surface stain-resistant against oil, wine, and citrus.

Frequently Asked Questions
Common questions about Calacatta Black Quartzite 3CM
Does Calacatta Black Quartzite 3CM need to be sealed?
Yes. Quartzite is a natural metamorphic stone and slightly porous - it should be sealed at installation and resealed every 1-2 years. Sealing keeps the surface stain-resistant against oils, wines, and citrus. We walk through care during the consultation.
Is Calacatta Black Quartzite 3CM harder than granite?
Yes - quartzite is typically harder than granite on the Mohs scale (around 7-7.5 vs granite's 6-6.5). It's one of the most scratch-resistant natural stones for a kitchen countertop, and well suited to heavy daily use.
How is quartzite different from quartz?
Quartzite is a natural stone (mined and cut from the earth, like granite and marble). Quartz is an engineered product (about 90% natural quartz aggregate bound with resin). Quartzite has the marble-like aesthetic of a natural stone but is harder than marble; quartz is non-porous and never needs sealing but doesn't have the unique character of true stone. Both are excellent kitchen countertops - the choice comes down to whether you want a natural-stone read or engineered consistency.
