What Causes Some Granite Countertops To Look Reflective?

If you’ve been looking at granite for your countertops, you’ve probably noticed that some granite’s have reflective areas that seem to sparkle in the direct light. But what causes this and how come some granite colors have more reflection than other colors? Granite is a crystalline, igneous rock that is comprised of a variety of minerals including quartz and feldspar. Other minerals such as hornblend, mica and occasionally pyroxene can also be present in the stone. It is the mica however, that gives granite its reflective appeal.

Mica is a mineral that is present in several forms including biotite and muscovite and is found in a variety of rocks. It has known for its unique reflective properties, as well as its basal cleavage, which makes it split, or flake easily off a stone.

The majority of granite’s contain some mica, but certain colors contain more depending on the stones mineral composition. It is these stones that contain large amounts of mica that are vibrant in direct light and are quite appealing to the eye. Many consumers are attracted to the bright blue and green mica colors. Others like the silver and gold colors in some stones with mica that give it mirror qualities.
