Beryl is a precious stone or gem, of a light or pale green colour, passing into blue and yellow. The beryl of the ancients is the same with what in latter times has been denominated aqua marina, on account of its azure or sea-green colour. Some authors take the beryl to be the diamond of the ancients; this is certain - the ablest modern jewellers sometimes mistake the one for the other. There are two species of this stone, the oriental or precious beryl, and the occidental or schorlous beryl; the former contains silex, alumina, glucine, lime and oxide of iron; the latter, silex, alumina, lime, and water. The precious beryl is much harder than the schorlous beryl. The beryl is sometimes found large enough to form fine vases. It is said that there are many of them in Cambaya, Pegu, and Ceylon. It occurs in considerable quantities in Saxony, Bohemia, and Moravia. The properties of the beryl were wonderful in the opinion of the ancient naturalists; it kept people, as they thought, from falling into the ambuscades of enemies; excited courage in the fearful, and cured diseases of the eyes and stomach; but all these qualities have vanished with the ignorance which gave them existence.
