Granite is defined as a coarse-grained igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground.


Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO3), otherwise known as calcium carbonate, and usually contains other minerals, such as clay, micas, quartz, pyrite, iron oxides, and graphite.


Dolomite is an anhydrous carbonate of calcium magnesium carbonate (CaMg(CO3)2). This class of stone is closely related to marble and limestone in its’ constituency but has an added mineral to make it uniquely different, namely, Magnesium. While it is considered marble, the addition of the Magnesium in dolomite enhances scratch resistance, heat resistance and staining and etching resistance.


Quartzite is a non-foliated metamorphic rock composed almost entirely of quartz. It forms when a quartz-rich sandstone is altered by the heat, pressure, and chemical activity of metamorphism. Metamorphism recrystallizes the sand grains and the silica cement that binds them together. The result is a network of interlocking quartz grains of incredible strength.


Onyx is naturally formed from calcite in caves around the world when water drips and evaporates from the ends of stalagmites and stalactites. Once it evaporates, it leaves behind traces of minerals and calcium carbonate which causes its intricate bands of varying colors. The bands of color are produced with alternating silica minerals – quartz and morganite – and leave behind bands that lie parallel to one another.


A metamorphic rock that consists primarily of talc with varying amounts of other minerals such as micas, chlorite, amphiboles, pyroxenes, and carbonates. It is a soft, dense, heat-resistant rock that has a high specific heat capacity.


Limestone is a sedimentary stone comprised mostly of decayed fish bones formed at the bottom of an ancient seabed. Over geologic time its Calcium Carbonate grains were compacted together enough to create the stone we know as limestone. Here as well, other mineral inclusions and binders give each limestone variety its unique coloration.


Travertine is a terrestrial sedimentary rock, formed by the precipitation of carbonate minerals from solution in ground and surface waters, or geothermally heated hot-springs.


Imagine being able to see your finished job before it even gets cut

Our SlabSmith technology allows us to overlay the templates of your project on the slabs you select so that you can see exactly how your project pieces will look before they are cut to make sure you get the exact flow, colors, etc. in the areas that you want them.

Once we have this virtual layout the way you want it, this digital information flows seamlessly throughout the entire production process, thanks to our cutting edge technology.

Monty B., San Antonio, TX
Michele and I want to thank Delta Granite for their beautiful work on our Vetrazzo recycled glass counter tops just installed in our newly remodeled kitchen. Even though we had to wait for them to be made and delivered, the experience that Delta provided was one of professionalism and attention to detail. Elizabeth our salesperson was informative during every step of the process. I never had to worry about anything as Delta was always there to handle everything. We would like to thank all of the employees who provided us service including Elizabeth, Liz, France, Bessie, Troy, Larry and the very experienced installers who worked very hard to make sure every detail of our installation was perfectly and professionally provided. I worried about nothing, and the job was done beautifully and efficiently. Their production and installation professionals did a fantastic job. We love our new kitchen thanks to Delta.
Ernest And Michele H., San Antonio, TX
Delta Granite and Marble, Inc. are so professional. They worked very meticulously to cut and place a very difficult piece of granite for me. They worked and worked on that piece until they got it absolutely right! The whole thing turned out perfectly wonderful! Very professional and the work ethic was beyond compare!
Jan H., San Antonio, TX

They came recommended to me by a relative, so I expected them to be a good reputable source for granite. However, I did not expect them to be outstandingly responsive to our remodeling schedule. From our first visit with Terry, our salesperson, to Troy’s measuring to France’s guidance through the process to Bessie’s brilliance on helping us craft our pieces from a beautiful slab, to the two installation technicians, we experienced nothing but excellence in service and attention to detail. They are uncompromisingly efficient and caring. Our scheduling changes were honored by them with professionalism and concern. We heartily recommend them to our relatives and friends as well. Good job, Delta!

Peggy C., Boerne, TX

Delta Granite and Marble installed counter tops in my kitchen and bathroom and they did a really professional job. They were very helpful and responsive to all my queries. They immediately gave me a pricing, complete with different options, so I had a clear idea right off the bat. I had checked with other places and hadn’t received this. I thought that was very helpful for us. They came to our place and took pictures, and provided us with all the information and guidance we needed to make the decision. They were great during the decision-making period and the work itself was also great. They did excellent installation and cleaned up after themselves. They gave us all the information we needed for every day maintenance before they left. Overall, it was a great experience.
