Onyx is commercially classified as a sibling to marble because these two stones have the same mineral content. Onyx is made of calcite, which is the same mineral that makes up limestone, marble, and travertine. In fact, banded calcite is a close cousin of travertine and forms in a similar way. Onyx is a product of spring water
Extraction of Egyptian Marble Most of the marble quarries in Egypt are located in the eastern desert, the Sinai region, and the Suez region. The extraction process involves cutting the marble blocks from the quarry using diamond wire saws, drilling holes along the sides, and then using explosives to break the blocks free.
