From Quarry to Countertop: The Journey of Granite and Marble
May 1, 2025
Understanding the Quarrying and Processing Techniques for Granite and Marble
Granite and marble are two of the most sought-after natural stones for countertops and vanities, prized for their aesthetic appeal and timeless elegance. But how does a raw stone from deep within the Earth become the stunning countertop or vanity that enhances your kitchen or bathroom? The process involves both intricate quarrying and careful fabrication to ensure each piece of granite or marble meets the desired look and functionality.
In this post, we'll walk you through the steps of quarrying and processing granite and marble, from their extraction in quarries to their final transformation into beautiful surfaces, including the crucial fabrication and installation process by companies like MGL Granite.
The Quarrying Process: Extracting Granite and Marble
The journey of granite and marble begins deep underground, where these stones are found in large deposits. Quarrying is the first step in bringing these raw materials to the surface.
1. Locating the Quarry
Granite and marble deposits are generally located in regions known for their unique geological formations. Granite is often found in large veins, while marble is typically found in areas that were once ancient seabeds. The best-known marble quarries are in Italy, Greece, and Turkey, while granite is extracted in countries like Brazil, India, and the United States.
Once the stone is located, geologists and quarry operators assess the quality and size of the deposit to ensure that the stone will meet the specific needs of countertop and vanity projects. This includes examining the stone’s patterns, color, and overall quality.
2. Extracting the Stone
The extraction process begins with the drilling of holes into the stone to insert explosives, which help loosen the large blocks of granite or marble. The stones are then cut free from the quarry using heavy machinery, such as diamond wire saws, which can handle the dense, tough material. These blocks of stone can weigh tons and must be carefully handled during extraction to prevent damage. After extraction, the large blocks are transported to processing facilities, where they will be cut into slabs for further refinement.
The Processing Process: Shaping the Stone
After extraction, the granite or marble blocks are ready for processing. This stage is where the raw stone is transformed into beautiful slabs that are suitable for use as countertops, vanities, and backsplashes.
1. Cutting the Stone into Slabs
At the processing facility, the first step is to cut the raw blocks of granite or marble into slabs of manageable size. This is done with industrial saws equipped with diamond-tipped blades. Depending on the size of the block, multiple slabs can be cut at once, maximizing the yield from each stone block. The slabs are typically cut to standard dimensions, such as 10 to 12 feet long and 1.25 to 2 centimeters thick, although custom sizes can be requested for specific projects. For particularly large blocks, multi-wire machines are used, which allow for more precise cutting, and the ability to cut several slabs at once.
2. Polishing and Finishing the Surface
Once the slabs are cut, they are polished to enhance the stone's natural color and veining. Polishing machines use abrasive pads and polishing compounds to give the stone a smooth, glossy finish. The level of shine varies depending on the desired finish—from a high-gloss shine to a matte or honed finish, which is particularly popular for marble in bathroom vanities. Granite typically features a glossy finish, which makes its natural colors and patterns pop, while marble, depending on the finish, can offer a more subtle elegance. Other finishes, like brushed or leathered, can also be applied, giving the stone a unique, textured look.
3. Fabrication: Customizing the Slabs
Once the slabs are polished and the surface is perfected, it’s time for fabrication. This is where the stone is cut and shaped to meet the specific needs of the project. At this stage, the fabricator, like MGL Granite, will customize the slabs for your countertops or vanities. Fabrication involves cutting out areas for sinks, faucets, and other features, as well as shaping the stone with edge profiles. Popular edge styles include straight, beveled, bullnose, ogee, and more (which we discuss further in a different blog post). The fabricator carefully measures and cuts the slabs, ensuring that the finished product fits perfectly within the intended space. The edges of the stone are also polished during this process to ensure they have a smooth, refined finish. Whether you prefer a sleek, modern edge or a more decorative profile, the fabricator can create the ideal edge for your design.
Quality Control: Inspecting the Material
At MGL Granite, we believe in ensuring that only the highest-quality materials are used in your project. Before we begin the fabrication process, we carefully inspect all the granite and marble material once it is delivered to us. This allows us to ensure that the stone meets our standards and is free of any defects that could affect the final product.
This step is crucial, as it ensures that we work with the best possible material before any cutting or shaping takes place, ensuring a flawless result for your countertops or vanities.
Transporting and Installing the Finished Slabs
After fabrication is complete, the granite or marble slabs are ready for installation. Once the finished slabs arrive at the job site, it’s time to set them in place. At MGL Granite, our skilled installers take great care in placing the slabs accurately, ensuring the seams are tight and the edges are polished to perfection.
During the installation, we also make any final adjustments necessary to fit the slabs to the exact dimensions of your kitchen or bathroom. Once in place, the stone is cleaned, and final sealing is often applied to protect the surface and enhance its durability.
Conclusion
The journey from raw stone to beautiful countertop or vanity is a carefully executed process, requiring expertise and attention to detail at every step. From quarry extraction to meticulous fabrication and expert installation, the process ensures that the final product is both functional and stunning.
At MGL Granite, we manage every aspect of the process—from the moment the stone is delivered to our facility, through the careful inspection and fabrication, to the final installation. Whether you’re choosing granite or marble, our team ensures that you get the highest quality stone and the best craftsmanship for your home.

Soapstone is one of those countertop materials that quietly commands attention—not with flash or trendiness, but with a natural, lived-in beauty that’s both rustic and refined. It’s been used for centuries in everything from farmhouse sinks to laboratory tables, and while it’s not as commonly seen in modern kitchens today, it still has a loyal niche following. At our shop, we can cut and install soapstone, and we’re happy to do so for clients who love its unique character. That said, we don’t actively promote it as a go-to countertop option—and here’s why. What is Soapstone? Soapstone is a natural, non-porous stone composed primarily of talc, which gives it a smooth, almost silky feel. It ranges in color from light gray to deep charcoal, often with subtle veining or marbling. One of its most distinctive features is how it darkens over time—a natural patina that many homeowners love for the warm, antique look it creates. The Positives of Soapstone Countertops 1. Beautiful, Aged Aesthetic Soapstone has a unique matte finish and soft veining that gives it an old-world, organic feel. Over time, it naturally darkens and develops character, which appeals to those who like the look of well-worn materials with a story. 2. Non-Porous & Stain-Resistant Unlike granite and marble, soapstone is naturally non-porous. That means it doesn’t require sealing and is very resistant to staining, even from red wine, citrus, or oils. 3. Heat Resistant Soapstone handles heat extremely well—you can place hot pots and pans directly on the surface without damage. It was historically used in wood stoves and chemistry labs for this very reason. 4. Low Maintenance No sealing is required. Most maintenance involves optional mineral oil applications to even out the darkening process and bring out the richness of the stone. The Downsides of Soapstone 1. It’s Soft—Really Soft This is the biggest tradeoff. Because soapstone contains talc, it’s one of the softest natural stones used for countertops. It can scratch, chip, and dent more easily than granite or quartz—especially in high-traffic kitchens. For this reason, we don’t actively promote soapstone unless a customer specifically requests it and understands the limitations. 2. Susceptible to Dents and Dings While scratches can often be sanded out or blended in with mineral oil, the material is more prone to nicks and damage from heavy use, dropped pans, or sharp objects. 3. Limited Color Range Soapstone comes in shades of gray, greenish-gray, or blue-gray. If you're looking for bright whites or dramatic patterns, it’s probably not your material. 4. Not as Widely Available Because demand is relatively low, not all fabricators or suppliers keep a wide variety of soapstone slabs on hand. Lead times can be longer, and slab selection may be limited compared to granite or quartz. Is Soapstone Right for You? Soapstone countertops are a great fit if: You love natural materials with a lived-in look. You’re drawn to vintage, farmhouse, or classic kitchen aesthetics. You’re okay with some surface wear as part of the stone’s evolving character. You want a low-maintenance, non-porous surface that doesn’t require sealing. However, if you’re looking for maximum durability with minimal maintenance or you want a material that’s resistant to scratching and chipping, there are likely better options for your lifestyle. Final Thoughts Soapstone isn’t for everyone—and that’s okay. While we’re more than capable of cutting and installing it for customers who love its charm, it’s not a material we push often because of its softness and wearability in busy kitchens. Still, for the right homeowner and the right design, soapstone can be a beautiful, one-of-a-kind addition with character you won’t find in more manufactured materials.
