Ruby is a pinkish red to blood-red colored gemstone, a variety of the mineral corundum (aluminium oxide). Ruby is one of the most popular traditional jewelry gems and is very durable. Other varieties of gem-quality corundum are called sapphires. Ruby is one of the traditional cardinal gems, alongside amethyst, sapphire, emerald, and diamond. [3]
By 1877, chemist Edmond Frémy had devised an effective method for commercial ruby manufacture by using molten baths of alumina, yielding the first gemstone-quality synthetic stones. The Parisian chemist Auguste Verneuil collaborated with Frémy on developing the method, but soon went on to independently develop the flame fusion process, which ...
The following are synthetic gemstones that were developed by Tairus scientists; they are alternately referred to as Tairus stones (e.g. "Tairus Ruby"). Floating zone ruby, synthesized in 1991 (no longer in production) Hydrothermal ruby, synthesized in 1992 by Alexander Dokukin. Hydrothermal aquamarine, synthesized in 1993.
The Verneuil process allows the production of flawless single-crystal sapphire and ruby gems of much larger size than normally found in nature. It is also possible to grow gem-quality synthetic corundum by flux-growth and hydrothermal synthesis. Because of the simplicity of the methods involved in corundum synthesis, large quantities of these ...

Auguste Victor Louis Verneuil (French:; 3 November 1856 – 27 April 1913) was a French chemist who invented the first commercially viable process for the manufacture of synthetic gemstones. [1] In 1902 he discovered the "flame fusion" process, called the Verneuil process , which is an inexpensive method of making artificial corundum , or ...
