Granite vs. Quartz Slabs: What Fabricators Should Know

Granite vs. Quartz: The Real-World Comparison

As a fabricator or buyer, you'll face this question constantly: granite or quartz? Both are dominant countertop materials, but they behave differently, price differently, and appeal to different segments of your customer base. Here's what you need to know.

Material Basics

Natural Granite

Granite is an igneous rock quarried from the earth. Each slab is unique — no two are identical. Colors range from basic blacks and whites to rare exotics in blue, green, gold, and red.

  • Origin: Brazil, India, Norway, USA, and many other countries
  • Composition: Feldspar, quartz, mica, and other minerals
  • Porosity: Porous — requires sealing annually
  • Heat resistance: Excellent — naturally heat-resistant
  • Hardness: Mohs 6–7 (very hard)
  • Engineered Quartz

    Quartz countertop surfaces are manufactured, not mined. They consist of approximately 90–95% crushed quartz crystals bound with polymer resins and pigments.

  • Origin: Manufactured in USA (Cambria), Spain (Silestone), Israel (Caesarstone), and Asia
  • Composition: Crushed quartz + resins + pigments
  • Porosity: Non-porous — never requires sealing
  • Heat resistance: Moderate — resin can discolor above 300°F
  • Hardness: Mohs 7+ (harder than granite in some specs)
  • Price Comparison

    CategoryGranite RangeQuartz Range
    Entry-level$10–$20/sqft$25–$35/sqft
    Mid-range$20–$45/sqft$35–$55/sqft
    Premium$45–$100+/sqft$55–$90+/sqft
    Exotic$60–$200+/sqft$70–$120/sqft

    Takeaway: Entry-level granite is typically less expensive than entry-level quartz. In the mid-to-premium range, they're often comparable in cost.

    Fabrication Differences

    For fabricators, the two materials behave differently under the blade:

  • Granite is harder and more abrasive — blade wear is higher. Cutting speed is typically slower.
  • Quartz is more consistent in density, which makes it easier to program CNC cuts. However, the resin can cause edge chipping if blades are dull.
  • Moisture sensitivity: Quartz should not be fabricated with excessive water pressure — the resin can delaminate.
  • Which Sells Better?

    Consumer trends as of 2024–2026:

  • Quartz dominates the mid-range remodel market — consistent color, no-maintenance pitch
  • Exotic granite commands premium pricing and strong demand in luxury kitchens
  • White quartzite (Super White, Taj Mahal) has surged as a marble alternative
  • Basic granite (Black Galaxy, Ubatuba, Uba Tuba) is a value play for budget projects
  • Inventory Strategy for Fabricators

    If you're buying slabs to stock your shop:

  • Fast movers: White/grey quartz, Black Galaxy granite, Colonial White granite
  • Margin drivers: Exotic granite (Titanium, Fusion, Blue Bahia), Calacatta quartz
  • Risk slabs: Trendy exotics — beautiful but slow to sell if customer changes their mind
  • Use BuySellStone to move slow-moving inventory and source hard-to-find slabs at wholesale prices.
