Understanding Grades of Granite

Almost everything that consumers buy has some type of rating system. Established by different organizations based on the specific product, these ratings help people choose what’s appropriate for their needs. 


Granite is a prime example, which also has a special rating system. Whether installed as countertop, flooring, or in outdoor spaces, this particular material offers tremendous value. For instance, granite is highly resistant to abrasions and chips. It can also withstand moisture, stain, and heat. Even when purchasing granite from the same distributor, slabs have individual characteristics, making each piece unique.

Granite Ratings

The rating for granite comes in the form of levels that go from one to three. To determine granite’s level, experts consider seven factors. These include:


  1. Colors

  2. Country of origin (quarried)

  3. Markings

  4. Pitting

  5. Soft materials quantity

  6. Thickness

  7. Veins


Listed below are the three levels for granite, along with a brief description of each.

  • Level 1 (low-grade granite)

Also referred to as either “builder’s grade” or “commercial grade,” this granite is of the lowest quality. That’s why it’s commonly used in apartments and prefab remodels. Unlike top-of-the-line granite with a thickness of 1/2 to 3/4-inch, level 1 is roughly just 3/8-inch.

Since level 1 granite is so thin, it usually needs added strength and support in the way of plywood backing. This low-grade granite typically comes from China. It’s then sold through big box stores or liquidators. Also, some companies cut this grade into tile, again used for low-end projects.

  • Level 2 (mid-grade granite)

Level 2 granite is a step up from level 1, meaning it’s better quality. Although this granite comes from different parts of the world, Brazil is among the biggest exporters. Not only is the thickness of level 2 granite 3/4-inch thick on average, but its colors and patterns create a more authentic appearance.

  • Level 3 (high-grade granite)

At the top is level 3 granite. This granite is among the finest available. For instance, slabs of this granite typically boast beautifully unique patterns, colors, and veins. Generally, Canada, Brazil or India offers this material. Although level 3 granite costs the most, it’s worth the investment. Sometime known as quartzite.

Incredible Versatility

With so much versatility, granite is a fantastic material for multiple applications. For one thing, you can choose from an assortment of color categories, such as white, black, brown, black and white, red, blue, green, and even pink. However, you can also choose from several edge profiles.


These include straight eased, ogee, bullnose, beveled, and waterfall. The combination of levels, colors, edges, and patterns gives you unlimited possibilities. Just remember that the key to achieving gorgeous countertops, floors, or outdoor living spaces comes down to getting granite from a reputable source.
