Ruby’s name is derived from the Latin term "ruber,” which translates to "red.” Historical records show that rubies were traded along the North Silk Road in China as early as 200 BC. Chinese aristocrats adorned their armor with rubies, convinced that the gemstone would offer them protection. After the depletion of classical Burmese mines, ruby production commenced in the Mong Hsu region of Myanmar in the 1990s. These rubies lacked the deep red hue typical of traditional Burmese rubies; they were subjected to heat treatment to improve their saturation and clarity. Despite their extensive history, rubies were not recognized as a variety of corundum until 1800. The red fluorescence exhibited by rubies played a significant role in the creation of the first operational laser in 1960. Currently, both natural and synthetic rubies are still employed in the production of lasers, watches, and medical devices.

Rubies can undergo various enhancements, including heat treatment, fracture filling, or diffusion. Untreated, natural rubies are typically regarded as rarer and more valuable compared to those that have been enhanced or treated, which affects their price and rarity. To clean rubies, use warm soapy water and a soft brush. It is advisable to steer clear of harsh chemicals, ultrasonic cleaners, and extreme temperatures. For rubies that have undergone treatments such as fracture filling, professional cleaning and assessment are also recommended.
