Granite is a stone quarried from the earth, and like any other natural substance, it has variations in quality. If you are looking for a slab of granite to use for a new project, then it is important to understand the differences in the grades of granite. Doing so will help direct you to the best fit for your needs.
So, how is granite graded?
It is graded into the three categories of low, medium, and high based on appearance, thickness, location, and porosity. These characteristics, as well as how unique the granite is, effects its grade. Identifying quality granite means you finding a slab of granite that has all the properties you have been looking for.
Granite is a great choice for countertops, around fireplaces or bathtubs, or even as flooring. Different grades are appropriate for different uses. What the project is and the budget will often determine what grade granite is the best choice.
So, How Do You Identify Quality Granite?
A good slab of granite will not have visible cracks, scratches, or dents. It will be free from these types of imperfections that could compromise its durability. Careful visual inspections are enough to determine if a slab is of a low grade with cracks or a medium or high grade with none.
Another important identifier of granite is porosity, or how much liquid it absorbs. If it is highly porous and absorbs lots of liquid, maintaining sealant is an important protection against spills and stains. Quality granite will either have low porosity naturally or will be installed with an excellent sealant.
So, What are Characteristics of the Three Grades?
A low grade of granite has all the great qualities of granite, including toughness and durability, but is found in a very common color pattern. Because the print is not unique, it is not considered unusual or high grade. Being cut thin, ½ inch or less, is also a characteristic of low-grade granite. It needs support from plywood or other backing when installed.
Medium and high-grade granite are at least ¾ inch thick and may not need other support when installed. They are also of the more unique color patterns that are not commonly found. If you fall in love with a pattern found only in one quarry in Italy, it will be considered high-grade granite because it is rare. A medium grade granite is not rare but not the most abundant, either.

So, When is it Worth it to Choose the Higher Grade?
You should consider looking at high-grade granite for any project that will highlight your granite as a main feature. If you are remodeling your kitchen and want your countertops to be a focal point, then it is worth the money for high-grade granite so that you can get the 1-inch slab from Brazil that has the perfect shade of blue running through it to match your cupboards. It is also worth the money for projects that need a thicker slab, such as an outdoor feature.
So, When Do You Choose Middle or Low Grade?
If you have a fixed budget to work with, then looking at slabs of middle and low-grade granite is a good idea. They may be shipped in from China or from a quarry on this continent to keep the price down. There are many patterns of granite that are beautiful even if they are common and affordable. This middle or low-grade granite could be used for apartments or other projects that need uniformity and longevity.
