Appreciate your granite countertops for all of their natural and intricate beauty. Marble and Granite has buyers throughout the world locating and selecting high quality granites with blends of minerals to provide unique colors and patterns for your home.

Granite is one of the most common igneous rocks used in residential design. Mined from all continents around the world, it is composed of numerous minerals that have fused together or formed under high pressure. Common minerals found in granite are quarts K-feldspars, plagioclase feldspars, potassium, and micas.

Quartz is one of the last minerals to form in granite. It acts as a bond between other minerals. Although it is colorless, it often appears gray because it reflects the colors of dark and light minerals around it. Mica is found in two major varieties in granite: muscovite, biotite and lepidolite. Muscovite and Biotite are forms of mica that quartz may reflect for its silver and black properties, respectively. In lepidolite form, mica may give granite a or violet of pink color.

Additional color sources in granite include K feldspars. K feldspars provide a variety of colors for granite including blues, blacks, pinks and yellows. Plagioclase feldspars are often white with a pearly finish.
