Orobico Black

The close-up view of each stone type shows a relatively true image of the crystalline structure and the colouring. This is suitable for grained slabs to a limited extend only. In regard to the colour matching, please take an original sample of the stone from your furniture store as a basis.

Petrography

The rock consists almost exclusively of calcite.

Petrogenesis

The originally light gray limestone evolved out of limescales on the seabed. The fine lined banding and the diverse embedded fossils result in a vivid texture.
