The different types of patterns and veins in marble and natural stone give a unique personality to each variety and even to each piece. As if it were a fingerprint, each type of marble or stone has a different pattern, and in addition, depending on the place and time of extraction, this pattern can be very different.
No two portions of marble are the same, no matter the size or the shape. There are no stone families according to the geometry of their veins , but it is possible to recognize some common features of lines. We describe them below.
Stones with linear veins usually have continuous, unidirectional, and bifurcated lines. The color of the veins is different from the background of the stone, generating beautiful contrasts.
Black Dune is an excellent example of marble with linear veins. It shows a magnificent contrast between its black background and the white veins that furrow it.
The marble with arborescent veins differs from the linear veins because its drawings are not unidirectional. Tree veins looks very similar to capillaries, and each branch can start a journey in a different direction.
Finally, we want to show Picasso Grey marble because it is halfway between the marble of linear veins and one of the tree veins of various colors (in this case giants). This example illustrates that not all the stones always fit perfectly in one or another “classification” by type of vein, as we mentioned at the beginning.
A breccia stone belongs to a geological formation in which marble was broken. It then generated large fragments of debris embedded later in another geological formation which crystallized as well. Hence, its appearance resembles a kind of massive terrazzo.
Visually, in marble or other stones with brecciated veins, it seems that some materials surround large “islands” that differ in typology and color.
The Arabescato Brescia is an example of breccia morphology. Thick brown lines surround portions of white rock.
The composition in the form of brocades is very similar to that of marble with breccias. However, in this case, the intermixed fragments are smaller.
Pacific Grey marble combines gray and white portions.
The fossils they contain inside create the shell stones drawings. In addition to some marbles, many limestones have this unique veinage, in which we can often recognize the conical shapes of Pleistocene mollusks.
