Let's start with the basics. You may be wondering, “how is granite graded?” There are a few factors that come into play when it comes to granite grading. Here's a bit on each to get you started:

GRANITE ORIGIN
We can source granite from across the world, and while granite from one place isn't necessarily better than that of another, it can impact the cost. For instance, ordering granite from China can be one of the most affordable resale options. However, when it comes from Brazil and Italy, it becomes more expensive.

As one would expect, granite is a heavy material, making it even more expensive to ship. So, where your granite is coming from and how it's being shipped can majorly impact your final cost. The most affordable option for a local remodel? Granite shipped within the U.S.

GRANITE THICKNESS
Granite is a natural material that is cut from the Earth. For this reason, it's often cut in giant slabs that then goes to a manufacturer who cuts it into pieces that are slimmer and more manageable. However, in an effort to make the slabs more convenient, manufacturers will sometimes cut them into super thin pieces, which ultimately negatively impacts the durability of each slab, particularly in cases when it is cut down to less than one inch thick.

For this reason, a thicker slab of granite is more durable and considered higher quality (and simultaneously will cost more!). When it comes to selecting a durable granite slab, look for 1 to 1 ? inch in thickness.

GRANITE VISUAL APPEARANCE
Let's face it - we definitely judge a book by its cover, and it's actually an important step when analyzing the grades of granite.

When looking at a granite slab, be sure to look for any scratches, dings, dents, or uneven areas. These imperfections may seem unique, but they can increase the chances that the slab will crack or break. A high-quality granite should have the strength to resist these marks and nicks, so if it already appears damaged, that's a pretty good sign it's not a high-grade slab.

GRANITE POROSITY
Porosity is key when selecting a durable stone. Based on the stones and minerals that make up your granite slab, the porosity can vary. In the long term, this can impact the appearance of your stone.

Additionally, if your granite is porous, it is more likely to stain as it will absorb liquid quicker without a sealant. In this case, maintenance requirements will also increase - something many of us with a busy lifestyle would like to avoid.
