What was the main material used in the construction of the Taj Mahal's dome?

The main material used in the construction of the Taj Mahal's dome is marble, particularly the white Makrana marble that is highly prized for its beauty and quality. This marble was chosen not only for its durability and aesthetic qualities but also for its ability to reflect light beautifully, which adds to the monument's ethereal appearance throughout different times of the day. The intricate patterns and inlay work found on the dome and the rest of the structure also showcase the marble's capacity to enhance the intricate craftsmanship that characterizes Mughal architecture. The glowing white surface of the dome contrasts dramatically with the gardens and the surrounding buildings, exemplifying the grandeur of the Taj Mahal as a mausoleum and a symbol of love. The other materials listed, such as granite, brick, and cement, are not primarily associated with the dome of the Taj Mahal and were not the main components in its construction.
