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 lime stone gets its lively ornaments from differing concentration of the colour pigment hematite. In this case, this is a chemically very stable red iron oxide, which is imbedded in very fine distribution in the main mineral calcite. This type of lime stone is very changeable; every plate is unique!
Lime stone has been generated by deposition of lime on the sea bed. In this case, also single-cell micro-organisms probably participated in the excretion of lime initially dissolved in water. Here, larger fossil inclusions cannot be recognised.
