Yellow gems have been called variations of the name topaz for thousands of years — long before mineralogists determined that topaz occurs in a range of colors, and that many yellowish gemstones actually belong to other mineral species.
Ancient texts from the Greek scholar Pliny to the King James Bible referenced topaz, but because of this longstanding confusion, they likely referred to other yellow gemstones instead.
During the Renaissance in Europe, people believed that topaz could break spells and quell anger. Hindus deemed topaz sacred, believing that a pendant could bring wisdom and longevity to one’s life. African shamans also treated the gemstone as sacred, using it in their healing rituals.
Russia’s Ural Mountains became a leading source of topaz in the 19th century. The prized pinkish orange gemstone mined there was named Imperial topaz to honor the Russian czar, and only royals could own it.
Since the discovery of large topaz deposits in Brazil in the mid-19th century, topaz has become much more affordable and widely available for all.
Processes were developed in the 1960s to turn common colorless topaz blue with irradiation treatment. This variety has since flooded the market, making it one of the least expensive gemstones available.
Light blue varieties of topaz can be found in Texas, though not commercially mined there. Blue topaz became an official gemstone of Texas in 1969, the same year Utah adopted topaz as its state gemstone.
