Marble is famous for the veining pattern that runs through every piece in a non-repeating pattern. As well as veining, marble will have natural variations in colour and gloss level across the surface. Common marble colours include white, white and grey (Carrara / Calacatta), and beige (Crema Marfil).
Strong coloured marble is also available, including greens, reds and blacks, but these are less common. The best identifier that they are marble is the heavy veining pattern that usually covers them. The rarity of these colours makes them more expensive, so they tend to be used in feature areas, benchtops, and vanities, and usually come in a high shine finish.
