Marble Countertops Colors

Marble countertops come in a huge collection of colors and shades.

Base colors

In its usual form, marble is fully white. The white comes from the high absorption of calcium in the marble. Marble is a metamorphic astounds, and is formed when limestone is subjected to very high pressures and temperatures in the Earth's crust. If the limestone is clean and reserved away from other substances, the ensuing marble will be a milky, transparent white.


Cream marble is colored with sand and is typically found near deposits of sandstone. The naturally brownish tenor of the sand mixes with the white of the calcium, producing a green cream color. Cream marble is also valued for the swirls and complicated designs usually found in it.


Gray marble can approach from coal mines or from a mixture of white marble and chert, a gray-blue sedimentary rock establish in the Earth's crust. Marble deposits found by coal mines get their gray color from the carbon satisfied of the coal. Gray marble can also be produced by the mixture of white marble and chert.


Iron ore deposits have a natural deep reddish tint can stain marble light pink to deep red, depending on the absorption. Extreme pressure in the Earth's crust presses iron ores and calcium limestone jointly, forming marble stones with a broad gradient of colors. Multiple shades of red can frequently be found in a single marble sample. Every shade, from a shy rose-like tint to wine-dark red, can be established in a single piece of marble.


Green marble is the result of the combination 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.
