The Masters of Crystal

Synthetic Corundum

Synthetic corundum, in the form of synthetic ruby, was the first gemstone reproduced by artificial techniques. Auguste Victor Louis Verneuil invented the flame-fusion technique (now know as the Verneuil method) of melting aluminum oxide and allowing it to recrystallize in a cone-shaped boule, the colour of which can be controlled by the addition of chemical additives.
