The first known reference to this sparkling stone as zircon was in an ancient Hindu poem about the Kalpa tree, described as a glowing tree draped with gemstones, with leaves made of zircons. It is referred to in the Bible under various other names, including the jacinth (red zircon) that is set in the breastplate of Aaron and as the stone given to Moses. Zircon is also among the "foundation stones" of Jerusalem's city walls in Revelations. Ancient gem lovers knew zircon as hyacinth, a name that is sometimes used to refer to the stone even today.
According to Jewish legend, the angel sent to the Garden of Eden to watch over Adam and Eve was named Zircon. Believed to be a symbol of honesty and contentment, zircon has also been thought to bring its wearers prosperity, peaceful sleep, honor, respect, and wisdom.
The Roman historian, Pliny the Elder, compared blue zircon’s color to hyacinth flowers.
Traditionally, zircon is a gem of purity and innocence. Zircon is believed to promote inner peace while providing the wearer with wisdom, honor and riches. Legend also has it that a zircon’s loss of luster is a warning of imminent danger.
Zircon’s popularity grew dramatically in the 16th century when Italian artisans featured the gem in jewelry designs. In the 1880’s blue zircon was widely used in Victorian jewelry.
