Granite Colors & InformationGranite is a tough, durable rock composed primarily of three different minerals. These minerals are easy to see due to their different colors. The white mineral grains found in granite are feldspar. It is the most abundant mineral found in granite. The light gray, glass-like grains are quartz, and the black, flake-like grains are biotite or black mica. Granite can come in several colors, depending on its origins. Barre Gray Granite from the quarries in Vermont is one of the most common types of granite used in cemeteries here. Prices vary with each different kind of granite and its origin of import.
Difference between marble and granite.
Although both are stones and both are quarried from the earth, granite and marble (and marble's relatives - limestone, onyx and travertine) are very different from each other. Granite is formed deep in the earth's mantle at extremely high temperatures, and is a very hard, resistant stone made of crystallized minerals. The marble family - limestone, travertine, marble, onyx - starts out as sediment - animal skeletons and shells, plant matter, silt - at the bottom of bodies of water. This solidifies (lithifies) into stone. Because its main component is calcium, it can be affected by acids such as vinegar and citrus beverages.
These are just a few examples of the granite colors available today:
