Dr. G. F. Herbert Smith says of this gem that it is of “a steely or greenish blue, not the royal blue colour of the glass models supposed to represent it.” If the accepted history of the stone be true, it must be regarded as a strange specimen. It was stated to have been discovered at the Kollur mines, and to have been purchased by Tavernier in 1642. In 1668, Tavernier interested Louis XIV in the gem so much that he purchased it. After this the fortunes of the great traveller began to change. His son defrauded him of a large sum of money, and he was later, being a Protestant, compelled by the Edict of Nantes (1685) to fly from France and seek protection in Switzerland. Thence he went to Berlin, where the Elector of Brandenburg offered him the Directorship in a projected East India Company. In the endeavor to find a road through Russia to India, Tavernier left Berlin, but he succumbed to fatigue and financial worry soon after, dying, it is said, in want, in his 84th year at Moscow. After wearing this diamond at a Court Ball, Madame de Montespan lost the favour of her Royal lover. It was a stone of ill fortune for Marie Antoinette, to whom, however, all diamonds were unfortunate. After the tragic death of Louis XVI and his Queen, the stone was stolen with the French regalia. Afterwards it is stated to have been stolen from Fals, the Dutch gem cutter, by his son. Fals died a broken-hearted man, and his son, after selling the gem to Francois Beaulieu, went insane and killed himself. Beaulieu, after selling the stone to Daniel Eliason, a London dealer, died suddenly the following day. Mr. Eliason sold it to Mr. Thomas Philip Hope, the banker, in 1830 for £18,000 sterling. Mr. Hope’s grandson, Lord Henry Francis Hope, married the Australian actress, Miss May Yohe, in 1894. This lady wore the diamond and misfortune followed her. In 1901 Lord Hope was glad to sell the stone to Mr. Weil, a London diamond merchant, who, without waiting for its influence to affect him, sold it immediately to Mr. Simon Frankel, jeweller, of New York, who suffered financial hardships consequent on the difficulty of finding a purchaser. At last he sold it to Mr. Jacques Colot, a French dealer in gems, and with it went his troubles also. Monsieur Colot quickly sold the gem to the Russian Prince, Kanitovski, and, it is stated, became insane and died mysteriously a few weeks afterwards. The Prince lent it to Mademoiselle Lorens Laduc of the Folies Bergeres, with whom he was in love. As she wore it one night on the stage the Prince in a mad fit shot her. A few days later he was himself stabbed to death by some members of a secret political club. The Blue Terror next came into the possession of the Greek jeweller, Simon Montharides, who, after having sold it to the Sultan, Adbul Hamid, was killed by accident with his wife and two children whilst driving. Abu Sabir, the Sultan’s lapidary, was entrusted with the polishing of the jewel, and whilst he had it he accidentally
