Product Overview

Marble is a natural stone that is made from limestone deposits that have been re-crystallized with applied heat and pressure.  As the deposits re-crystallize, the marble is morphed into its signature colors, swirls, veining, and patterns creating a wide range of unique looks.  Marble surfaces have been admired for their aesthetics since ancient times and marble countertops can provide a nice touch of beauty and sophistication to kitchens and bathrooms.  Graniterra offers marble countertops formed from limestone deposits imported from quarries around the globe.

Marble Ratings

Marble is typically given a soundness rating by the Marble Institute of America to determine its quality.  The ratings range from A to D with A being the highest rating.  Once a marble slab is installed, the soundness rating only reflects the appearance of the marble.  The basic criteria for the grades of marble are listed below:

  • Soundness Group A: Marble surfaces in this group have few geological flaws and voids with subtle veining and muted colors.
  • Soundness Group B: This group has few flaws but may have micro to medium levels of fissures and pitting.
  • Soundness Group C: This group may have geological flaws, voids, veins, or lines of separation that are typically repaired at the factory.
  • Soundness Group D: This group contains even more variations than Group C that are factory repaired. Marble of this grade has brighter colors with decorative veins and swirls.

Finishes

Marble countertops are available in two main finishes: polished and honed.  Polished marble has a very shiny finish that creates a mirrored look.  Honed finishes are created by removing the top layer of marble to leave a smooth, satin finish.  Both types of finishes should be sealed for protection.

Marble Countertop Maintenance

Marble is a popular choice for countertops not only because of their unrivaled beauty, but also because of their durability and easy maintenance.  With the proper care, marble countertops can last several lifetimes.  The following are marble countertop maintenance tips:

  • Make sure marble countertops are sealed regularly.
  • Polished marble countertops may need re-polishing for a renewed shine.
  • Put pads or pot holders under hot pots and serving dishes and avoid putting hot items directly on the counter.
  • Make sure to clean up any spills immediately with mild detergent.  Marble countertops can stain.
  • Avoid using abrasive cleaners on polished marble, the surface can scratch and chip.
