“After an exhaustive search and visits to many granite suppliers, I chose Keystone Granite for my complete kitchen upgrade.

What is Granite?

Granite is an igneous rock made of at least 10% quartz and a combination of other minerals, mostly feldspar. Igneous means it formed due to the hardening of molten magma, and it did so in large crystals which you can clearly visible in the processed and polished rock. This is the reason it is called “granite,” referring to the granular nature of the patterns.

Quartz is one of the hardest minerals in the world and has no color. Feldspar, the most abundant group of minerals on Earth, is made of silica and alumina. The combination of quartz and feldspar yields light-colored stone. However, it is possible to have dark minerals thrown in the mix. This gives granite a unique pattern of colors that permits no duplication, naturally or otherwise. Each granite slab installed in the home is different, even if they all came from the same stone.

Uses of Granite

There are many uses for granite, primarily as a smooth surface. It is quarried as a dimension stone, which means the source stone as blocks and slabs for decorative and structural use. It has been used as such for centuries, and it is the most abundant type of rock on Earth. Getting the best stones out, however, requires extensive experience and knowledge. It is useful for paving, flooring, gravestones, facing stones on buildings, and fireplace surrounds. Its most popular use, however, is for work areas such as vanity tops and countertops because of its durability and strength.


Granite is very durable, able to withstand quite a bit of weight provided it gets the proper support. You need to get a professional installer to assess your needs for your new granite countertop. The greater the percentage of quartz in the slab, the more durable it is. It is also proof against most stains and scratches, and can withstand quite a bit of heat. Overall hardness depends on the amount of quartz it contains, which can be anything up to 50%. This is the reason why it is very popular as kitchen countertops.


The reason granite is so strong is because it was formed under great pressure. This makes it very dense, and mostly nonporous. Geologists call it “poor primary permeability,” which means water and other fluids do not easily get through past the surface, but when it does, it does create a stain. This is the reason why it is sealed periodically to keep liquids from getting past the surface. A properly sealed slab makes for a very good countertop.


Granite is low maintenance as long as the seal remains intact. Keystone Granite recommends researching every one to three years, depending on use. Keeping it in pristine condition typically requires a regular application of warm water and mild detergent. It is important to remove liquids clean from granite surfaces as much as possible, especially anything containing acid or oil. Check out Granite Gold
