3. What is the color of granite?

Minerals give the colors to the granite. These gorgeous stones are most commonly pinkish, white, and variations of grey and black. Sometimes you can see “black granite” in the market. These are not granite but gabbro because granite must contain at least 20% quartz within a rock to make it granite. Gabbro is a variation of basalt. Mainly, these stones are all formed from cooled lava flows.
