A Timurid carved marble panel is the star lot of Bonhams' forthcoming Islamic and Indian Art sale.
It's expected to make £80,000-120,000 ($113,709-170,564) in London on April 19.
The Timurid Empire was established by the Mongol warlord Tamerlane and occupied much of Central Asia between 1370 and 1507.
This carving is believed to have been created to adorn the back of a throne and dates to the middle of the 15th century.
It was the custom of Timurid rulers to receive guests in their gardens. The fact the piece is carved from marble indicates the throne was located outside.
The reign of the Timurids saw a flowering of Islamic art and architecture, centred around the capitals of Samarkand and Herat.
The soaring domes and elaborate facades proved a major influence on Indian art.
A diamond, ruby and gold Manga Malai necklace originating from Southern India in the 19th century is valued at £50,000-70,000 ($71,076-99,506).
The design is only found in the south of India, where the mango is a symbol of fertility.
It would have been worn during weddings and is being consigned by an Indian royal family living in the UK.
It's a spectacular item and could easily exceed its valuation. A similar specimen realised £84,100 ($135,090) against an identical estimate at Sotheby's in 2014.
