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.
An exceptional Gabbro with irregularly embedded veins of accumulated mica.
As those are softer than the surrounding areas, the surface shows slight depressions and gives a pleasant feel. The main minerals are pyroxene and plagioclase feldspar.
Gabbro (named after a place in Tuscanny/Italy) is a magmatite rock. Big magma bubbles solidified very slowly under highly stable cooling conditions at a depth of several kilometres. It was only after the removal of the covering layers in the course of millions of years that the solidified magmatite rock was brought to the surface and can now be quarried in large blocks.
