This item is not a scepter, as many would naturally assume. Rather, it is a jewel-encrusted battle mace. It was a favorite of Fathali Shah, who is often shown holding it in his miniature portraits.
The mace is encrusted with spinels and diamonds, from end to end. It is 73 cm. (2.4 ft.) long. The largest diamond weighs 17 cts., and is located on the very top of the mace. The largest spinels are the six surrounding the top of the mace, each weighing 40 cts.
