Stucco decorations are present on the medallions of the interior arches. The squinches have converted the second storey into an octagonal conformation. Piercing on each side of them provide ventilation. No monument have been built over the grave. There is also no tombstone. At the time of construction, the interior was covered with glazed tiles which have currently been destroyed. The drum from which the dome rises is cylindrical externally and circular internally. Red stone bricks have been used in the construction of the drum. The sotiff of the dome contains an arabesque design made using blue and red coloured tiles. The brick built dome is complementary to its drum. The dome was covered with turquoise blue tiles. From these, the building gets its name Nila Gumbad which in English translates to "Blue Dome". A "kalasa" finial crowns the dome.
