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.
Estremoz is an extremely fine crystalline, homogeneous marble, the colour spectrum of which ranges from cream to pink. Veins of very different shades (dark red, green, grey, olive) may penetrate the rock more or less intensely. The pigmentation results from deposits of microscopically small hematite scales (iron oxide),sepentinite or graphite in and between the calcite crystals.
Marble generated in general by metamorphosis (rock transformation) of limestone. During the earliest earth ages, in the Portuguese marble province, a limestone massif with low iron content reached lower zones of the earth due to earth crust movements and was then covered in layers of sediment rock. Over of millions of years, the limestone then re-crystallised into marble under the influence of pressure and temperature. The intense pink colouring was generated by iron oxide, originally contained in the limestone.
