The so-called “black onyx” has almost entirely replaced jet. This is a chalcedony impregnated with a carbonic matter, such as blood or a solution of sugar, the carbonate of which is charred by sulphuric acid, giving a rich, velvety, black hue to the stone, which takes a high polish. However, a certain limited amount of the old “Whitby Jet” once so highly favored is still mined and worked up into ornaments in the neighborhood of Whitby on the northeast coast of England, in the district of Leeds, although but fifty persons are now engaged in this industry which fifty years ago gave employment to 1500 workers. Some Spanish jet is also used, a material harder and more brittle than that found in England.

The story was current that Pope Leo X (1475–1521) had a precious stone, probably some type of “moonstone,”[[676]] which grew brighter as the moon waxed, exhibiting the soft, silvery brilliance of our satellite, and then gradually lost its brightness as the moon waned, growing paler and dimmer and becoming quite obscure as the moon’s disk ceased to be illumined by the sun. As a mate to this, Pope Clement VII (1475–1534) was reputed to have in his possession a stone with a golden spot which moved across the surface in exact accord with the apparent motion of the sun across the heavens from sunrise to sunset.[[677]] These are undoubtedly fables that were circulated intentionally, or more probably through pure love of exaggeration, in order to enhance the merit of two exceptionally fine specimens of moonstone and sunstone in the papal treasury.
In the eighteenth century the collection of the Duke of Brunswick contained a magnificent ancient drinking-cup, of the kind used in sacrificial ceremonies, cut from a single piece of onyx; this cup was said to have formed part of the rich spoils taken from Mithridates by the Romans under Pompey. It was valued in the duke’s inventory at 150,000 thalers, and Catherine II of Russia is stated to have offered four times that sum, or 600,000 thalers ($400,000) for this unique cup.[[678]]
In the symbolism of the Manichean sect, an early Christian heresy owing its origin to a direct and predominant influence of Persian ideas, pearls occupy a prominent place. A legendary or poetic pearl called “the bright moon” was the symbol of compassion, and one of the treatises ends with the words: “Our heart has received the majestic splendor of the pearl granting every wish.” We are also told of “a diamond pillar” which sustains humanity, and the Messenger of Light is likened to a perfumed mountain entirely composed of a mass of jewels.[[679]]
The recital of two Arab travelers, Hasan ibn Vazid and Sulaiman, who visited India in the ninth century, contains a curious theory of the formation of pearls or rather of the pearl-oyster. The primal matter is assumed to be a gelatinous moss, analogous to that of a species of algæ. This floats upon the water and attaches itself to the keels of ships, where it hardens, develops a shell, and finally drops off to sink into the depths of the sea. The formation of the pearl itself is then discussed and the theory noted in Pliny’s Natural History and so often repeated after his time, namely, that pearls are formed from the “dew of heaven,” is cited; but the writer adds: “Others say that they [the pearls] are produced in the oysters themselves. This appears more probable and is confirmed by experience; for the greater part of those observed in the oysters are firmly attached there and are immovable. Those which are mobile are called by the merchants seed-pearls.” As a true Mohammedan the writer concludes with the pious ejaculation: “God knows how the matter really stands!”[[680]]
The same travellers relate the story of the discovery of a pearl under very singular conditions. An Arab came to Bassora with a very fine pearl. He took it to a druggist whom he knew and asked the latter how much it was worth. The merchant estimated it at a hundred pieces of silver, to the great surprise of the Arab, who demanded whether anyone could be found willing to pay so much. Without hesitation the merchant declared that he was ready to give the price himself, and immediately paid over the money. He then took his purchase to Bagdad, where he secured a large profit on his investment. On concluding his sale the Arab told the Bassora druggist how he had secured his pearl. One day, while walking along the Bahrein coast, he saw on the sands a dead fox, whose mouth was tightly compressed by a strange object. On closer observation this proved to be an enormous pearl-oyster shell. Evidently the fox had thrust his snout into the shell while the valves were open so that he might devour the soft contents, but the valves suddenly closed upon him and he had died of suffocation. On prying open the shell the Arab found therein the pearl which was destined to bring him what he regarded as a fabulous sum.[[681]]
The women of the Arab town occupying a site close to that on which stood the Babylon of ancient times, wore, as a favorite adornment, nose-rings of gold set with a pearl and a turquoise. The English traveller, John Eldred, who traversed Mesopotamia in 1583, found this custom so general that he writes: “This they doe be they never so poore.”[[682]]
For years a statement has been going through the press that pearls are liable to become diseased and die, and that the famous necklace of pearls presented by President Thiers of France to his wife, and bequeathed by Mme. Thiers to the French Government, had lost their lustre and died, perhaps owing to the death of the owner. For there is an old belief that pearls, as well as opals and turquoises, lose some of their lustre when the owner or wearer becomes ill, and change to a dull and lifeless hue when the owner dies. An examination of the necklace by the writer showed that the pearls were in good condition, and to confirm his statement to this effect he had the director of the Louvre Museum write him a letter. In this official communication the director not only states that the pearls had not sickened and died, but that they were in as “healthy” a condition as they had ever been.
