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.
Three main components make up the rock: Pale grey KNa- feldspar and white NaCa feldspar, often in large crystals, pale grey, transparent quartz, scattered like pearls - and black biotite in scaly agglomerations up to 10 mm in size and silvery glistening muscovite.
At medium depths, during the upper carbonaceous, some 300 million years ago, magma penetrated between the strata of the earth's crust and solidified so slowly (over millennia) that large and distinct crystals of each component were formed. More recently exposed at the surface by folding.
