What it evokes
Modern crystal practice associates zircon with focus and renewal: it is said to be chosen to stay on course in a task or to mark a new beginning.
The story of its name is rich. It comes from the Persian zargun, “gold-colored”; yellow, orange, or red zircons were long called hyacinth, and clear ones jargon. Kunz reports that in India hyacinth was dedicated to Rahu, the “dragon” of eclipses, and was believed to ward off misfortune. Australian zircons are among the oldest dated minerals on Earth.
It is worn as a reminder of endurance.
The traditions
- Middle Ages and Europe
Kunz reports that hyacinth was recommended to travelers as an amulet: it was credited with protecting them and winning them a good welcome at the inn. It was believed to lose its luster when its wearer or a relative caught the plague, and to increase its owner’s wealth. Old stone names shift, and the exact identity of this stone remains uncertain.
Gutenberg 57978, Kunz 1913, chapter “Jacinth” (hyacinth, equated with zircon by the index) - India
Kunz notes that one of the Sanskrit names for hyacinth, zircon, is rahuratna, the “jewel dedicated to the dragon” believed to cause eclipses of the Sun and Moon. Because the stone was consecrated to this dreaded power, it was believed to turn aside misfortune. A Hindu list of month stones, which he also reports, gives it for September.
G. F. Kunz (1913), passage on the stones of India - 1952 list
Zircon was added in 1952 to the December birthstones, with turquoise; the current Jewelers of America list no longer gives lapis lazuli, which zircon therefore replaced. Kunz’s Hindu list, which gives it for September, shows that the month of a stone varies from one tradition to another.

Nuances and sources
Zircon is a natural mineral, not to be confused with cubic zirconia, a synthetic material: the names are alike, the stones are not. Most blue and colorless zircons in the trade are heated, which the site’s profile notes; Cambodian blue zircon is heated to obtain that shade. Links to signs and chakras vary.

Zircon: your questions
Zircon or cubic zirconia: what is the difference?
They are two different materials. Zircon is a natural zirconium silicate; cubic zirconia is an oxide made in a lab, often sold as a diamond imitation. Zircon is heavier, and it is softer than zirconia, but the eye alone is not enough to tell them apart. Ask for the exact designation and, if need be, a gemologist’s opinion.
Is a blue zircon natural?
Its blue color is almost always obtained by heating: brown zircons, once heated, become blue or colorless. The stone remains a natural zircon, but the seller must disclose the heating. The site advises against strong heat: avoid leaving the jewelry near a radiator or on an exposed windowsill in midsummer.
