Jet
Jet has been found among the palæolithic remains in the caves of the “Kesslerloch,” near Thayngen, Canton Schaffhausen, Switzerland. The material was evidently derived from the deposits in Würtemberg and was shaped by flint chips. Quite possibly jet, as well as amber, was already regarded as possessing a certain talismanic virtue. Such ornaments, when worn, were believed to become a part of the very body and soul of the wearer, and were therefore to be guarded with jealous care.[115] In the palæolithic cave-deposits of Belgium also, jet appears, the supply being in this instance derived from northern Lorraine. The fragments had been rounded and pierced through the centre.[116] This indicates their use as parts of a necklace or as pendants. Necklaces, bracelets, and rings were especially favored for the wearing of talismanic gems, since the stones could easily be so set that they would come in direct contact with the skin.
Jet was one of the materials used by the Pueblo Indians for their amulets. An exceptionally well-executed figure of a frog made of this material was found in Pueblo Bonito, in 1896, by Mr. Pepper. The representation is much more realistic than is the case in the other figures of this type from this region. Turquoise eyes have been inserted in the head of the figure and a band of turquoise surrounds the neck.[117]
