Experiments in the synthesis of rubies and sapphires began in the 1860s, but it was not until the birth of the Vernier furnace in the early 20th century that the synthesis of red and sapphires was really successful. The synthesized red sapphire is crystallized from the melt, and its main components are Al2O3. When a trace amount of Cr is added during synthesis, it is red, that is, synthetic ruby; If a trace amount of Ti is added, it becomes a synthetic sapphire.

Synthetic rubies and sapphires are very similar in appearance and properties to natural red sapphires, so it is difficult to distinguish them. It is mainly based on the differences in inclusions inside the sample to identify, such as synthetic red sapphire often contains bubbles, fine arc lines and so on. If the inclusion is small, these phenomena may not be observed with a magnifying glass, and you need to use an optical microscope to observe them.
