Katuba Blue

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 gneiss consists mainly of light feldspar and changing proportions of dark silicates (biotite, amphibole). The occurrence of the blue mineral sodalite, concentrated mostly along former faults, is extraordinary, but it can also be interspersed into the matrix. Also smaller quantities of calcite are part of the existing mineral contents.


Gneiss is generated from rocks of magma and sediment origin under high pressure and temperature. A clearly direction-orientated structure is generated hereby, but also the mineral content may change significantly.
