Why International Stone Quarries?

Natural stone is quarried throughout the world in a variety of colors with varying mineral compositions, and our mission is to bring to you the most amazing selection available in all those quarries.

What is a marble?

Marbles are traditionally prized for their aesthetic appeal. This calcareous stone is composed mainly of calcium carbonate, a chemical compound commonly found in natural stones, shells, and pearls. As calcium carbonate is sensitive to acidic solutions so mild, non-acidic cleaners are recommended.  Some are accentuated by pronounced veining trends and bold colors. Often included in the marble family are serpentines and onyxes.

What is a granite?

Granite is an igneous stone that typically exhibit small flecks or grains of minerals uniformly distributed throughout the stone. This stone is generally resistant to most acids found in kitchen settings, although acidic cleaners are still not recommended, as these stones may contain trace of minerals that are acid sensitive.

What is a quartzite?

Quartzites are generally harder and denser than granites with patterns that can resemble veining found in many marbles. Quartzite is a naturally occurring stone that is highly resistant to chemicals and scratches. Quartzites should not be confused with manufactured quartz-based materials.

How should I clean my countertop?

  • Clean stone surfaces with a neutral cleaner, stone soap, or a mild liquid dishwashing detergent and warm water.


  • Similar to any item cleaned in your home, an excessive concentration of cleaner or soap may leave a film and cause streaks. Follow manufacturer recommendations.


  • For best results, use a clean rag mop on floors and s sift cloth for other surfaces.


  • Rinse the surface thoroughly after washing with soap solution and dry with soft cloth.


  • In the bath or other wet areas, soap scum can be minimized by using a squeegee after each use. To remove soap scum, use a non-acidic soap scum remover or a solution of ammonia and water. Frequent or over-use of an ammonia solution may eventually dull the surface of some stone types.


  • In outdoor pool, patio, or hot tub areas, flush with clear water and use a mild bleach solution to remove algae or moss.

Should I seal my countertop?

Sealing is a common step taken on some stones as an extra precaution against staining, In fact, the sealing products used in the stone industry are “impregnators” which do not actually seal the stone, but more correctly act as a repellent rather a sealer. Sealing does not make the stone stain proof: rather, it makes the stone more stain resistant. If a sealer is applied in a food preparation area, be sure that it is non-toxic and safe for use.
