For thousands of years, eye­ catching granite has been known for its unyielding endurance, which is why it has become a staple in the home, from countertops to floors. However, it is one of the most difficult stones to polish, especially black and red granites. Granite polishing is a painstaking process, demanding ten times the honing with diamond abrasives as marble polishing does.

Granite can become dull and damaged through daily wear and tear or scratches. Because granite has such a high concentration of quartz, it can be scratched by the traces of quartz in tracked­ in soil. While these individual scratches are nearly invisible, over time they can accumulate and noticeably mar the surface of highly polished granite.
