What are the Different Types of Stone for Countertops?
With a seemingly endless array of the different types of stone for countertops and other installations, it’s helpful to know a little bit about each material and how it relates to your space.
Granite is one of the most abundant natural stones on the planet. It forms the bulk of the earth’s crust and is formed under high heat and pressure deep underground. Along with natural abundance, it comes in a large variety of colors. The incredible forces that create granite also cause it to be a very durable stone. It consists of mostly quartz and feldspar which give it a natural strength. This is one of the different types of stone for countertops that performs exceptionally well over time with minimal maintenance. Granite is ideal for practically any installation, indoors or out, kitchen or baths. It ranks a 7 on the Mohs scale of hardness.
This metamorphic stone is well known for its use in famous buildings and sculpture around the world. It comes in a variety of colors and patterns, depending on where it’s quarried. Because it’s made of metamorphic limestone, marble is very porous in nature. For this reason, it can be susceptible to staining if not treated and sealed regularly. For the same reasons, it can also etch from coming into contact with acidic foods or liquids. Marble is one of the different types of stone for countertops and is a more high-maintenance stone than others, for this reason, we don’t recommend using it in high traffic/high use areas like a kitchen.
Limestone is a sedimentary rock composed of ancient corals and marine organisms. Often times, you can see the actual shells and shapes of fossilized animals in the stone. In Texas, it’s frequently used in exterior construction and is also known as “Austin Stone.” The most common type of limestone that we use to make countertops come from Spain and other places around the world. Due to its porous nature, we don’t recommend using limestone in heavy use areas. Limestone is very susceptible to staining and etching.
Travertine is a type of limestone formed by hot springs. The movement of water gives travertine its familiar stripes and the gasses within cause bubbles and holes within the stone, which we call pits. Coloration stays very neutral, beige and gray being the predominate tones. As with Limestone, it’s porous and s one of the different types of stones for countertops that is not suitable for high traffic areas and is subject to staining if not sealed often.
A stone that is gaining in popularity, quartzite is composed almost entirely of quartz in various forms. Found around the world, quartzite comes in a wide variety of colors and patterns. Formed under extreme pressure, this stone is remarkably hard and rates from 7-8 on the mohs scale. In addition to hardness, it is also very stain resistant. This makes it ideal for a wide variety of installations.
Composed primarily of talc, soapstone is a very soft material sometimes used for countertops. Color options are limited as it only comes in varying shades of gray. Most slabs are smaller than 7 feet meaning a project is more likely to have seams. Because of its softness, it can easily be scratched. Over time, soapstone will darken. Even though it is soft, Soapstone is non-porous and resistant to staining. Unlike the different types of stone for countertops, soapstone should never be chemically sealed. Mineral Oil is used to give soapstone its rich finish.
Commonly known by popular brand names like Maestro Quartz, Caesarstone, Silestone and Cambria, man-made quartz products are a rapidly growing segment of the countertop market. Composed of crushed natural quartz, color pigments and resin, these products resist staining and are very hard. They are suitable for many types of indoor installations.
