Description : side by a baguette-cut diamond, with a round diamond gallery, mounted in yellow gold " Signed by Cartier, #43-19991 " " The word "emerald" is derived from a Persian word which has reached us through such altered forms of Latin as " smaragdus, esmeraude " and " esmeralde. " In its present form, the word appeared in English in the 16th Century. " " To the Ancients, these green stones had enormous amuletic significance. They believed emeralds would "drive off vain fears and evil spirits, strengthen the memory, reveal adultery, give knowledge of the future, produce eloquence and increase wealth." The most potent of all superstitions about emeralds was that the scoothing green color could control optical disorders. It is said that Nero peered at the burning of Rome through an emerald lens so the heat of the flames would not injure his eyes. In the treasure of the Shah of Persia is an emerald box, said to have been blessed by the Prophet Mohammed, which has the ability to render the royal owner invisible --as long as he remained celibate! " " It is likely that all emeralds known in ancient times came from the so-called Cleopatra mines in Upper Egypt. These mines were abandoned and their location so completely lost that many gemologists maintained that emeralds had never been found in Egypt at all. " " Doubts about the matter were put to rest in 1818, however, when the mines were rediscovered by a Frenchman, F. Caillaud, who was commissioned by the Viceroy of Egypt to search for them. The mines were found to have been heavily overworked at various times in history, and after a few years were closed, only to be reopened again at the end of the 19th Century. They were finally closed once more, never to reopen, since the stones recovered were of inferior quality. " " The most important source of fine emeralds today are the mines near the villages of Muzo, Chivor and Somondoco, some 75 miles from Bogota, Colombia. When the Spanish Conquistadores captured the Inca Empire and took possession of a vast treasure, they found immense numbers of emeralds, some of incredible size, in the temples and on the persons of the Incas themselves. To protect the location of the mines, the natives destroyed all traces, and the thick, impenetrable tropical jungle swallowed them up. Neither persecution nor torture could induce the Incas to reveal the source of their wonderful green stones, and it was not until 1558 that one of the mines was rediscovered by accident. " " The Columbian mines have remained the major source of emeralds that are superior in color and freedom from imperfections than those from any other source, although stones from the Ural Mountains in Russia, from Africa and more recently, from Brazil must not be overlooked. " " Emeralds were eagerly sought by the Indian Maharajahs, and many of the Princely houses assembled enormous collections of the largest and finest stones. An outstanding example of the richness of these hoards may be found in the Iranian Crown Jewels, which were taken at the conquest of Delhi in the 17th Century and for over three hundred years have formed the basis for the Iranian monetary system. " " Emeralds came to be associated with India (even though no significant deposits are found on the subcontinent) during the 1920s and 1930s when the Maharajahs were having them recut to suit more contemporary mountings. It was also at this time that many of the major jewelry houses in Europe and America acquired many of the magnificent stones that appear from time to time in the saleroom. ".
