3. Q. Is the marble covered by the same 15-year limited warranty against staining?
 

Stonemark granite is inherently much more stain- and etch-resistant than any marble. For this reason, marble does not carry the same 15-year limited warranty as the Stonemark granite.

Stone selection:
1. Q. Are all granites alike?  
 

No, your slab is hand selected by our worldwide team of certified inspectors. Any slabs that do not conform to our highest quality standards are rejected. Our slabs are premium grade, with guaranteed quarry-to-customer quality. In addition, each Stonemark countertop has the added protection of PermaShield – a process that makes Stonemark stain resistant and virtually maintenance free. Backed by a free 15-year limited warranty, and surprisingly affordable, there is simply no other stone like Stonemark.

2. Q. Should I view my Stonemark granite slab prior to fabrication?

All Stonemark granite is rated with the Innovative Stone Classification System. Please refer to the Material Gallery for details.

3. Q. Does the quality of stone matter?

All Stonemark materials are carefully selected and inspected prior to installation in your home. Only the highest quality of stone will be used to ensure years of use and enjoyment of your stone countertop.

4. Q. What is Natural Stone?
 

Natural Stones are classified as igneous, metamorphic and sedimentary based on their geological formation. There are many different types of natural stones including granite, marble, limestone, sandstone, soapstone and schists. Granite is the most common and most suitable natural stone for countertops. Please refer to the section on Natural Stone Information for more detailed information.

5. Q. What is the difference between Granite and Marble?

In broad geological terms, granite is an “igneous” rock formed by intense heat, which liquefies rock deep in the Earth and which solidifies upon cooling. Marble is a "metamorphic" rock resulting from the re-crystallization of limestone under intense pressure and high temperatures within the Earth. Stones falling within the same geological class share the behavioral characteristics, which determine the appropriate application. In general, granites are much harder and less porous than marbles, which makes them more suitable for kitchen countertops.

6. Q. Can I use marble on my kitchen counters?

Marble may be used for kitchen counters but they require special maintenance and care, and they are not covered by the Stonemark warranty.

7. Q. Where does my stone come from?
 

Our Stonemark stones come from quarries all over the world. Details of country of origin and other information on each stone is available in the Material section of this website.

8. Q. What is the difference between granite and a man-made countertop?  

Granite is a 100% natural surface and its beauty cannot be duplicated. Granite is also fire proof and will not burn. Man-made surfaces (also known as engineered stone) are bound with resins that will burn.

9. Q. Can it be used outdoors?

Yes granites can be used for outdoor applications, the warranty will not apply to these installations.

10. Q. What is the weight of Stonemark per sq. foot? Does the weight vary depending on the type of stone?

The weight of natural stone will vary depending on the stone you choose. For example, light colored marbles like Carrabianco will weight less than darker colored granites like Luna Nero. The difference will usually be 1-2 lbs per square ft. The list below will show you the difference in weight of a 12 x 12" tile by thickness.

  • 3/8" x 12x12 Granite tile: 4.5-5.5 lbs sq. ft.
  • 1/2" x 12x12 Granite tile: 5.5-6.5 lbs. sq. ft.
  • 3/4" x 12x12 Granite slab: 11-12 lbs. sq. ft.
  • 1 1/4"x12x12 Granite slab: 16-18 lbs sq. ft.
