White Granite



You are likely to have dark streaks or specks in there, which are most likely amphibole. White granite forms because conditions did not favor the formation of more amphiboles, or there simply weren’t other minerals from the source material.

Does raw granite sparkle?

After it is initially polished at a fabrication facility, granite is able to produce a natural shine. This is largely due to the high quartz content present in the stone. The amount of shine you will see from your granite will largely depend on the finish of the stone.

Is mica found in granite?
