A round, granite top patio table can come in a variety of colors. Light colors are usually flecked with darker colors, which can be reds, blues, slate grey or even black, depending upon the minerals that are present where the granite is harvested. Granite should not be confused with marble, which will have different colors and is usually cut from a slab. Granite tabletops are sometimes formed from scraps of other granite projects. The easy way to select your granite table top is to visit a company that makes tables. There you can select a top, including the color and shape, and possibly select the stand upon which it will be placed.
