Manufacture of Precious Stones.

Since science has demonstrated that artificial rubies can be manufactured, there is little doubt that before long diamonds and other gems will also be turned out from the laboratory. It can scarcely be said that made rubies are not genuine, as they differ in no respect of material or appearance from the stones manufactured by nature, but it is declared possible to distinguish them by means of a microscope. It is a curious caprice that will discard an article as spurious merely, because it is turned out of the laboratory of man instead of nature, especially when there is no difference between the two products.
