Indian (Mughal) khanjhar (curved dagger). Circa 1615-1620, this dagger and scabbard, thought to have been commissioned and designed by Emperor Jahangir around 1619, is a masterpiece of 1,685 rubies, 271 unpolished diamonds, 62 emeralds, 321 pieces of transparent emerald-green glass, 39 pieces of blue glass, 9 pieces of ivory and 6 layered agates – making a total of 2,393 stones, plus another 26 which are now missing. It is elegantly set with rubies to form patterns of birds and flowers.
