Granite Countertops—Spotlight On Mica!
From time to time, we get customers out to our showroom who have seen a certain color they were drawn to. Most people are unsure of the color names, but they are always quick to describe the granites with reflective colors. While all granite is composed of a variety of minerals including quartz, and feldspar, it is the mica that gives some granites those reflective, mirror-like deposits.
Some customers are drawn to granite colors with mica in them because when direct light shines on the stone, often times the mica will appear to change, such as from blue to green. This can be seen in colors such as Black Polar Russian, Labrador Antique, Emerald Pearl, Mermaid Green, etc. Other granites with mica deposits have a silver, or gold sparkle to them. This can be seen in colors such as Black Galaxy, Silver & Gold, Cosmos, Silver Galaxy, etc. According to Wikipedia, “The word “mica” is thought to be derived from the Latin word micare, meaning “to glitter”, in reference to the brilliant appearance of this mineral (especially when in small scales).”
Following are a few photos of granite with mica that I wanted to share:
