varying according to the specimen. The most valuable of all diamonds
are the red. This color is very rarely found, and there are only a few

Old Mine stones
are supposed to be fine blue-white or extra fine white stones from the
old Brazilian or Indian Mines, and originally were always cut in such a
manner as to save the most weight; consequently, they were frequently
very thick and of poor shape. Today we hear very little about Old Mine
stones, since as fine stones have been found in South Africa as were
ever found in the Old Mines, and those that are shown as Old Mine
stones are generally "fakes," coming from regular sources.
