In the famous Hungarian crown, the large sapphire is surrounded with four green stones of oblong form, whose species are unknown. It is also a mystery how they came there, as they are not mentioned in the inventory made of the jewel when Queen Elizabeth of Hungary pledged it to the Emperor Frederick IV. The Sultan of Turkey is known to possess some exquisite emeralds; and Rambusson, a French writer on gems, declares that they are the finest in the world. One of them is said to weigh one hundred and twenty-five ounces, and is probably another lump of antique glass. Another of three hundred karats weight, and of less doubtful character, is a gem of great purity and perfection of color. It adorns the handle of a poniard. In the museum at Florence there is a small vase carved in emerald, and also another ornament of similar form, fashioned from a fine beryl. The mineralogical collection at Munich boasts of some immense emeralds which are supposed to have been obtained from Spain, and part of her Peruvian booty. There are also some splendid specimens of uncut emeralds in the cabinet of minerals at Vienna. The Saxon and the Papal crowns contain very beautiful emeralds. Probably the most beautiful specimen of the natural emerald in the world is that presented to the renowned shrine of Loretto in Italy, by Don Pierre Daragon, when Spanish ambassador at Rome. He was formerly viceroy in Peru and obtained the treasure at that time. The specimen is a mass of white limestone, crowned with great crystals of emeralds more than an inch in diameter and of exquisite color and lustre. The name of Emerald Isle is generally supposed to have been derived from the ever green appearance of its shores but an antiquary asserts that it arose from the ring which was set with “Optimo Smaragdo,” and which Pope Adrian sent to King Henry II. as the instrument of his investiture with the dominion of Ireland. There is a very fine and large crystal of emerald in the museum at Leiden, but its history is unknown. Dhuleep Singh of India possesses a flattened crystal of three inches in length by two in width, and half an inch in depth, which is regarded as of great value in India. It is said to be of very fine color and with but few imperfections. The Duke of Devonshire’s crystal in its natural state is reckoned as one of the finest, if not the finest single specimen in the world. It is from Muzo in New Granada, and more than two inches in length. Its form is that of a hexagonal crystal, and its weight is 8 oz. 18 dwts. The color of the stone is beautiful, but several flaws impair the value as a gem.
