Forest Brown

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

As a rule, serpentinite is a dark green rock, mostly showing a tangle of white veins. In this case, green serpentine exists at most as relics. The bulk of this mineral has been converted and impregnated by brown limonite. The earthy, widely spread progressivelygradedshades of colour combine with the matt surface, which cannot be polished, to allude to organic materials, like wood or leather. 

Petrogenesis

Serpentinite has been generated under conditions of metamorphosis (conversion under high pressures and high temperatures in the earth crust). Olivine-rich magma rock like peridotite or picrite were converted, whereby the mineral olivine became serpentine.
