A common Swiss soldier, who discovered the body in a ditch, found the jewel in the clothes, and, not knowing its value, sold it for a florin...
PÓgina 10 - The cause of the wonderful brilliancy of the diamond is not popularly known. It has no inherent luminous power ; it is simply transparent, like common glass, and yet, if the latter were cut into the form of a brilliant, it could no more be mistaken for a real one than for a sapphire or an emerald.
