Precious Stones of the Americas

The four rain-making gods are shown wearing necklaces of coral and turquoise in the ceremonial sand-paintings of the Navajos. These four gods are respectively colored to denote the four cardinal points; black for North, blue for South, yellow for West, and white for East. The whole painting, measuring nine by thirteen feet, is guarded on three sides by magic wands; toward the East it is left unprotected, as only good spirits are believed to dwell in this direction. Each of the raingods carries suspended from his right wrist an elaborately decorated tobacco pouch, bearing the figure of a stone pipe. The Navajos believe that in this pouch the god places a ray of sunlight with which he lights his pipe; when he smokes, clouds form in the sky and the rain descends. In the sand-picture representing the God of the Whirlwind this divinity also wears ear-pendants and a necklace of turquoise. (Alfred Marston Tozzer, "Navajo Religious Ceremonials, Putnam Anniversary Volume, New York, 1909, Plate II.)

Of the turquoise in Aztec times we have the testimony of the missionary Bernardino de Sahagun that one variety, presumably that regarded as the finest and most attractive, bore the name teuxivitl, which signified "turquoise of the gods." No one was allowed either to own or wear this as it was exclusively devoted to the service of the gods, whether as a temple offering, or for the decoration of the divine images. Sahagun describes this turquoise as "fine, unspotted and very clear. It was very rare and was brought to Mexico from afar. Some specimens were of rounded shape, like a hazel-nut cut in half; others were broad and flat, and some were pitted as though in a state of decomposition." (Sahagun, "Historia general de las cosas de Nueva Espana," Mexico, 1830.)

The god of fire, Xiuhtecutli, or Ixcocauhqui, presided over the ceremony of piercing the ears of the young boys and girls. The image of this god was decorated with ear-rings encrusted with a mosaic of turquoise. He held in his left hand a buckler on which were five large green stones called chalchiuitl (jadeite), placed in the form of a cross on a plate of gold almost covering the shield. (Sahagun, l. e., 1829.)

At the time of the Spanish Conquest an immense emerald, almost as large as an ostrich egg, was adored by the Peruvians in the city of Manta. This "emerald goddess" bore the name of Umina, and, like some of the precious relics of the Christian world, was only exhibited on high feast days, when the Indians flocked to the shrine from far and near, bringing gifts to the goddess. The wily priests especially recommended the donation of emeralds, saying that these were the daughters of the goddess, who would be well pleased to see her offspring. In this way an immense store of emeralds rewarded the efforts of the priests, and on the conquest of Peru all these fine stones fell into the hands of Pedro de Alvarado, (Garcilasso de la Vega, "Histoire des Incas." Fr. trans. by Jean Baudoin, Amsterdam, 1715.) Garcilasso de la Vega, and their companions. The mother emerald, however, had been so cleverly concealed by the priests of the shrine that the Spaniards never succeeded in gaining possession of it. Many of the other emeralds were destroyed because of the ignorance and stupidity of some of their new owners, who, supposing that the test of a true emerald was its ability to withstand hard blows, laid the stones on an anvil and hammered them to pieces. The old and entirely false notion that the genuine diamond could endure this treatment may have suggested the unfortunate test.

Garcilasso likens the growth of the emerald in its mine to that of a fruit on a tree, and he believed that it gradually acquired its beautiful green hue, that part of the crystal nearest the sun being the first to acquire color. He notes an interesting specimen found in Peru, half of which was colorless like glass, while the other half was a brilliant green; this he compares with a half-ripened fruit. (Ibid.)
