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.
Fine-grained, extremely compact quartzite with blue colouring mineral inclusions. Different concentrations of dumortierite effect the wavy, striped or cloudy structure and make Azul do Macaubus one of the most beautiful stones in the world. The colour spectrum reaches from white-blue to a rich azure blue. However, nearly always, several shades are present in one block. The yellow to brown veins and inclusions originate from mineral iron ore. Almost every plate can be looked at as a unique specimen due to the strongly varying colour runs.
Azul do Macaubas was generated by metamorphosis of quartz-rich sandstones. During this metamorphosis, the individual quartz bodies of the former sandstone were fused at the edges with one another - a process establishing the extreme strength of this scratch-resistant hard rock.
