Firishta's History (Gulshan-i Ibrāhīmī) 67.2.4

67.2.4

I have heard old persons, who saw the Tukht-i-Feroza in the reign of Sooltan Mahmood Shah Bahmuny, describe it as being six cubits long, and two broad: the frame was of ebony covered with plates of pure gold, inlaid with precious stones of great value, in such a way as to be taken off and put on with ease. Every sovereign of the Bahmuny dynasty added some rich jewels, so that in the reign of Mahmood Shah, when it was taken to pieces, in order to remove part of the stones to be set in vases and goblets, the jewellers valued the whole at one crore of hoons. I learned, also, that it was called Feroza from being enamelled of a sky-blue colour, which was in time totally concealed by the number of precious ornaments.
