What Colors & Available For Marble Countertops?

Marble countertops come in a huge array of colors and shades. A marble countertop typically has a base color and is stained with other colors in irregular patterns, to make a natural look.

Base colors

In its usual form, marble is totally white. The white comes from the high attention of calcium in the marble. Marble is a metamorphic rock, and is created when limestone is subjected to very high pressures and temperatures within the Earth's crust. If the limestone is clean and reserved away from other substances, the ensuing marble will be a milky, transparent white. This is the rarest and most valued variety of marble, and is frequently used for sculptures and statues.


Cream marble is also valued for the swirls and intricate designs usually found in it. The patterns usually look like quietly curved lines, which are really internal cracks caused by the great pressure than the marble sustains through formation.


Gray marble can come from coal mines or from a mixture of white marble and chert, a gray-blue sedimentary rock found in the Earth's crust. Marble deposits found near coal mines get their gray color from the carbon content of the coal. Gray marble can also be created by the mixture of white marble and chert. Such marble varieties are much lighter than carbon-stained marble. While viewed under intense light, chert-stained marble can have a bluish tint.


Iron ore deposits have a usual deep reddish tint can stain marble pale pink to deep red, depending on the concentration. Extreme pressure in the Earth's crust presses iron ores and calcium limestone mutually, forming marble stones with a wide incline of colors. Multiple shades of red can often be found inside a single marble sample. Every shade, from a timid rose-like tint to wine-dark red, can be found in a single piece of marble.


Green marble is the result of the synthesis between serpentine and marble stone. Serpentine is a magnesium-rich silicate with a little crystalline nature. Green marble has a more crystalline look and is so more refractive, that is, more glossy than other colors.
