Properties of the Stone
Quarry Site and Nomenclature
Egyptian Pegmatite is a natural stone quarried from Wadi Umm Shegilat in the Gebel Abu el-Hasan region of Egypt’s Eastern Desert. Italian stonemasons referred to it as ‘Granito della Collona’ due to its frequent use in columns.
Technical Characteristics
This stone is characterized by its mottled light gray, pale pink, and greenish-black, and is mainly coarse-grained. It is classified as a magmatic rock of the diorite pegmatite type.
Use in Roman and Ottoman Architecture
The Romans extensively used Egyptian Pegmatite for its durability and aesthetic appeal in architectural projects, including columns, statues, and various ornamental elements. It was commonly employed in monumental buildings and public structures. During the Ottoman Empire, Egyptian Pegmatite was used as cladding on the exterior walls of the Revan Pavilion in Topkapı Palace. Its continued use in later periods further emphasizes its lasting value as a building material.
