From what type of stone is the Taj Mahal built?

The Taj Mahal is predominantly built of white marble embedded with semi-precious stones. Other structures within the mausoleum complex are layered with red sandstone, including the main gateway, mosque and "jawab."

The Taj Mahal in Agra, India is a renowned architectural marvel that is considered to be a World Heritage site. It was erected to serve as the resting place of Mumtaz Mahal, the favored wife of the Mughal emperor Shah Jahan.

The building materials were imported from central Asia and various regions in India, including the white marble that was transported from Jodhpur to Agra. The tomb's elaborate design utilized an inlay technique called pietra dura in which semi-precious stones, such as lapis lazuli, jade, crystal, turquoise and amethyst, are cut and fitted into the white marble to form multicolored patterns.
