A comparatively recent attempt to use diamond dust as a poison is said to have been made in 1874 on Colonel Phayre, British Resident at the court of the then reigning Gaikwar of Baroda. The colonel was in the habit of refreshing himself after his morning walk with a glass of sugared water flavored with a little lime-juice. One day, on taking a sip of his customary beverage, he noted that it had a strange taste, and instead of drinking it he saved it up and had it analyzed. The analysis revealed the presence of arsenic in quantity sufficient to cause death, and of diamond dust as well. Here, as in the case of Sir Thomas Overbury, the really innocuous diamond material was accompanied by an actual poison. The current belief in the poisonous quality of the diamond is reflected in the words “mortal as diamond dust,” used by Horace Walpole in one of his letters to the Countess of Ossory.[666] A German writer of the seventeenth century quotes with admiration a wonderful tale told by Johannes Bustamantius to the effect that he had seen a marriage of two diamonds, the two crystals being so firmly drawn toward each other by mutual sympathy that when they were put in one place they would cling to one another, as with an “unending kiss,” as though one were a man and the other a woman, and he asserts that the union was blessed with offspring. This curious idea has been repeatedly put forth by certain of the older writers as we have had occasion to note elsewhere.[667] After expatiating on the mechanical skill displayed by the Indians of the New World, an early Spanish traveller gives the following details regarding their success as gem-cutters:[668] Yet all that we have said is surpassed by the ingenuity of the Indians in working emeralds, with which they are supplied from the coast of Manta and the countries dependent on the government of Atacames, Coaquis or Quaques. But these mines are now entirely lost, very probably through negligence. These curious emeralds are found in the tombs of the Indians of Manta and Atacames; and are, in beauty, size and hardness superior to those found in the district of Santa Fé; but what chiefly raises the admiration of the connoisseur is, to find them worked, some in spherical, some cylindrical, some conical, and of various other figures; and all with a perfect accuracy. But the unsurmountable difficulty here is, to explain how they could work a stone of such hardness, it being evident that steel and iron were utterly unknown to them. They pierced emeralds and other gems, with all the delicacy of the present times, furnished with so many tools; and the direction of the hole is also very observable; in some it passes through the diameter, in others only to the centre of the stone, and coming out at its circumference they formed triangles at a small distance from one another, and thus the figure of the stone to give it relief was varied with the direction of the holes.
