The thirteenth century Hindu physician Naharari states that the topaz tastes sour and is cold. It is a remedy for flatulence and is a most excellent appetizer. Any man who wears this stone will be assured of long life, beauty and intelligence.[323] Many a curious legend has been woven about the old belief that the topaz quenched thirst. However, popular fancy does not endow any and every topaz with this power. One of these thirst-removing topazes is said to have been in the possession of a celebrated Hindu necromancer, whose services had been sought by one of the petty rajahs of India on the day of a decisive battle. Either this necromancer’s art must have failed him at the critical moment, or else a more powerful enchanter guided the fortunes of the enemy, for the latter prevailed and the owner of the potent topaz was left dying upon the field of battle. Alongside him was a poor wounded soldier who was clamoring for a drop of water to quench his burning thirst. Hearkening to this prayer, the dying necromancer threw his topaz to the soldier, telling him to place it upon his heart. No sooner did he do so than his thirst passed away, and we must suppose that his wounds were also healed, for we are told that on the morrow he sought everywhere on the battle-field for the corpse of his benefactor but could find no trace of it.

These were often cut from the top of the crystal, usually darker in color, and simply domed off, preserving the original hexagonal shape. Remarkable specimens are in the Indian Museum and the South Kensington Museum, part of the jewels of Thebaud, King of Burma. The finest emeralds of this type belonged to the late Sultan of Turkey; one of the finest, a remarkable gem, cut rounded en cabochon, was with the Bijoux du Sultan, S. M. Abd-Ul-Hamid II, sold at the Galerie Georges Petit, November 28, 1914. It weighed 44³⁄₁₆ carats (old system) or 45.29 carats (metric system). (See color plate.) A remarkable charm is a hemispherical, transparent aquamarine, with figure of hump bull, found in ancient Babylonia. (See color plate.)
