Igneous Stone

The hardest, most durable natural stone — built for daily use across 100 years.

Granite is an igneous rock formed by the slow crystallization of magma beneath the earth's surface. Composed primarily of quartz, feldspar, and mica, it's the most common exposed rock on earth's continental surface and one of the hardest building stones (Mohs 6–7). Its interlocking crystal structure makes it virtually impervious to staining or etching.

Surface options

Polished

Mirror finish, maximum color depth. Standard for kitchen countertops and lobby floors.

Honed

Matte satin. Contemporary and fingerprint-forgiving. Popular for modern kitchens.

Flamed

Torch-textured, rough surface. Maximum slip resistance. Standard for exterior steps and paving.

Brushed

Wire-brushed texture. Aged, natural feel. Great for outdoor kitchen counters and fireplace surrounds.

Leathered

Matte textured finish. Hides fingerprints and water marks. Growing in popularity for kitchen countertops.

Pros & cons

Advantages

  • Hardest natural stone — virtually scratch and etch-proof
  • Near-zero water absorption — naturally stain resistant
  • Outstanding freeze-thaw performance
  • Ideal for outdoor kitchens, commercial flooring, exterior
  • 100+ year lifespan with minimal maintenance
  • Widest color and pattern range of any stone

Considerations

  • Heavy — 13–15 lbs/sq ft for 3cm slab
  • Seams visible on countertops over 10 ft long
  • Must be professionally cut and installed
  • Large-pattern slabs can look busy in small kitchens
  • More expensive than tile or engineered options

Granite — common questions

Granite is extremely scratch-resistant (Mohs 6–7 — only diamond or carbide scratches it). It's also highly stain-resistant when sealed — its low porosity means liquids don't penetrate easily. Acidic foods and beverages do NOT etch granite the way they etch marble. For most homeowners, sealed granite requires minimal maintenance.
Natural granite: 100% natural, unique patterns, higher heat resistance (can set hot pans directly on most granites), UV-stable for outdoor kitchens, and adds premium resale value. Engineered quartz: more uniform patterns, non-porous (no sealing needed), but can discolor from UV and is damaged by excessive heat (the resins degrade). For outdoor kitchens, granite is the clear winner.
Granite is available in the widest color range of any natural stone: white (Alaska White), black (Absolute Black from India), grey (Viscount White), blue (Azul Bahia), green (Ubatuba, Verde Butterfly), red (Raspberry Red, Baltic Brown), gold (Giallo Ornamental, Santa Cecilia), and brown (Tan Brown, Baltic Brown). Each quarry produces unique patterns — no two granite slabs are identical.
Dense granites (Absolute Black, Baltic Brown) may never need sealing — they're so dense that water doesn't penetrate. Light or porous granites (White Ice, Kashmir White) need annual sealing. Do the water-drop test: place a few drops of water on the stone. If they bead for 4+ minutes, the sealer is active. If they absorb quickly, reseal.
Yes — granite is one of the best outdoor stones. Its near-zero water absorption (0.05–0.2%) means freeze-thaw cycles cause minimal damage. It's UV-stable and chemical-resistant. Flamed or brushed finishes add slip resistance for outdoor steps and paving. Granite is the standard material for commercial plazas, building base courses, and outdoor kitchen countertops.

How to Choose and Fabricate a Granite Countertop

From slab selection to installation — a complete guide to granite countertop projects.

1

Visit the slab yard in person

Granite slabs vary enormously within a single color name. Visit the stone yard and select specific slabs — ask the yard to pull them out so you can view them vertically at eye level. Bring cabinet door samples and flooring samples for reference. Mark your slabs immediately with chalk or tape.

2

Measure and template

Have a professional fabricator template your kitchen AFTER cabinets are installed. Templates create exact cutouts for sinks, cooktops, and edge profiles. CNC-cut granite tolerates no error — never accept a countertop fabricated from a hand-drawn sketch.

3

Select edge profile

Eased (flat, softened corner): modern and easy to clean. Bullnose (rounded): classic, comfortable. Ogee (S-curve): traditional elegance. Waterfall (90° vertical edge): contemporary. Mitered (two pieces joined at 45°): creates thick appearance. Edge profiles are cut simultaneously with fabrication — decide early.

4

Inspect before installation

Before installation, examine the finished pieces for chips, cracks, or color inconsistencies. Check that seams will fall where planned and that patterns align at key locations (around the sink, at islands). Small adjustments are possible before installation; none after.

5

Seal and maintain

Apply penetrating sealer before use. Most fabricators seal during installation. Reseal annually with a granite-specific impregnating sealer. For daily care: pH-neutral cleaner, dry with a soft cloth after each use, use trivets for pots.
