Silva Verde Nero

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.


This is a rock with very complex composition. The main minerals are transparent quartz (which is hardly visible) and light plagioclase feldspar. The green silicates like chlorite, epidote and hornblende dominate regarding colour.  


A rock type formed under high temperatures and pressures from a granite. Reason for these extreme conditions was the uplift of the Alps. During the increase of the pressure and also after the decline of the enormous exposures, very complicated mineral metamorphoses happened, which have stimulated various scientific dissertations.
