According to the Greeks, the gods of heaven and earth gathered at the Blue Topaz, where they deliberated on the exclusion of evils in order to make the sky and all the seas appear transparently blue.
The name topaz derives from the Sanskrit word Tapas main course, which means heat or fire. The stone symbolizes the fresh glow of youth and, for those who believe in forces of nature and astrology, its astrological purpose is to bring new life and positive energies. For the Hindu religion, it is the stone of the “Kalpa tree” and is believed to be one of the 9 sacred stones of the religion.
Blue topaz is extremely rare in nature and one of the most popular gemstones in the world along with rubies, diamonds and sapphires. The intense blue color observed is the result of applications of gamma radiation or other types of radiation on naturally colorless topazes, a specimen found only in Sri Lanka.
Blue topaz has colors ranging from a very light blue, almost white, to a dark and deep blue, which can be achieved with methods involving gamma radiation. Some shades are so characteristic that there is a specific nomenclature for them on the market. Broadly speaking, they are classified into three categories based on color.
