A unique gemstone form composed of opaque red Ruby in contrasting green Zoisite is well known from Tanzania, and is used as a minor gemstone and can be carved into ornaments.

Inclusions can also help identify the source of a ruby. See our article on identifying the origins of rubies and sapphires for more information.

Lab-created ruby can be manufactured by several different methods, including flame fusion , the Czochralski process , flux , and hydrothermal.

Flux-grown ruby crystals. Corundum gemstones, both rubies and sapphires, were first synthesized in the late 19th century.

In , the French chemist Auguste Verneuil published his work on the flame fusion process, still known today as the Verneuil vair-NAY process.

As a result, the production of synthetic rubies and sapphires skyrocketed. The second heating process can be repeated three to four times, even applying different mixtures.

In , Gaudin made the first synthetic rubies by fusing potash alum at a high temperature with a little chromium as a pigment.

In , Ebelmen made white sapphire by fusing alumina in boric acid. In , Verneuil announced he could produce synthetic rubies on a commercial scale using this flame fusion process, later also known as the Verneuil process.

Other processes in which synthetic rubies can be produced are through Czochralski's pulling process , flux process, and the hydrothermal process.

Most synthetic rubies originate from flame fusion, due to the low costs involved. Synthetic rubies may have no imperfections visible to the naked eye but magnification may reveal curved striae and gas bubbles.

Imitation rubies are also marketed. Red spinels , red garnets , and colored glass have been falsely claimed to be rubies.

Imitations go back to Roman times and already in the 17th century techniques were developed to color foil red—by burning scarlet wool in the bottom part of the furnace—which was then placed under the imitation stone.
