What Are The Different Grades Of Granite Countertops?

Granite countertops enhance kitchens and bathrooms, blending with any decor. Formed from lava and rock, they resist damage. Sealing extends durability for decades. Grades A, B, and C classify granite quality.

How Do You Determine The Grade Of The Granite?

There are three primary grades of granite countertops: Level 1 (low-grade granite countertops), Level 2 (mid-grade granite countertops), and Level 3+ (high-grade granite countertops). 

The grade of a granite slab is mainly determined by its colours, veins, pitting, marking, thickness, the amount of soft material it contains, and the country where it was quarried.

The structural quality of a granite slab is what we call its "grade." When dealers grade slabs of granites, they look at several identifiers. Richness and scarcity of colour usually offer good clues to the granite's quality.

Slabs with more unique colours, veining, and patterns will be given a higher grade than others.
However, the granite's grade is also impacted by factors such as pitting and marking on the surface, the thickness of the slab, and the amount of soft materials present.

Despite what many people think, there is no set industry standard for grading granite countertops. Most companies that sell granite have their own system for classifying it, which although similar to other systems in place, will often differ slightly between vendors.

Consequently, the level at which one wholesaler operates may be completely different from another. Always source kitchen countertops from a reputable and knowledgeable company to avoid any issues and to agree on a final cost.

How Thick Should the Granite Countertop Be?

Granite is a natural material that comes from the Earth. That's why you often see it in huge slabs at a manufacturer. They cut it into smaller pieces that are easier to use.

However, sometimes manufacturers cut slabs into thin pieces which makes them less durable. This is often done when the slabs are very thin, such as when they are cut down to less than one inch thick.
A thicker slab of granite is both more durable and automatically deemed as high quality ( for a price).

When trying to select a long-lasting granite, look for one that lies between 1 to 1 ¼ inches in thickness.

What Each Granite Grade Means | Granite Grading

Level 1 Granite - otherwise known as low-grade granite, entry-level granite, commercial-grade granite, and builder's-grade granite - is a lower-quality granite option. This type of granite typically comes from China, is pre-fabricated, and is often seen in apartments or homes that are being remodelled.

A level 1 granite slab is only ⅜ inch thick and will require a plywood backing to make it more long-lasting.
Even though it's given a low grade, that doesn't mean the slab won't look nice! It often features a basic design without much colour variation, making it perfect for people who want something more subtle.

More budget-friendly than other similar options on the market, this granite stone is perfect for anyone looking to stay within their means.
Level 2 mid grade granite typically originates from India or Brazil and provides more color, designs, and variation than Level 1. 

If you're looking for a unique granite look that includes various patterns, then consider selecting level 2.
This stone is about ¾ inch thick, which makes it more durable and a better investment than lower grades of stone. It's also perfect for those who want something more unique, but don't want to spend the price on high-grade granite.
High quality granite is mported from India or Brazil, high-grade granite of level 3 and up is among the finest quality stones available. It boasts an incredibly unique appearance.

Level 3 granite slab is usually 1 to 1 ¼ inches thick, making it extremely durable. And while location doesn't necessarily dictate quality, it can fluctuate granite countertops cost.
Plus, it often has an intricate design with highly varied colour patterns and depth, making it the perfect choice for those looking for a stunning appearance in their remodel.

High-grade quality granite does have a higher price tag. But due to its thickness, high-grade granite countertop is a worthy investment for anyone looking for something unique and durable.

Ultimately, the grade of your granite countertop will come down to personal preference and budget. You'll also find rare colours, patterns, and veins running through it for a truly unique finish. It's important to remember that the grades don't stop at 3! Some places offer grades as high as 7 for an even higher quality stone.
