Zircon is brilliant. It flashes multiple colors of light called fire. Its sparkle and flashes are diamond-like, so for centuries, there was a lot of confusion between the two gems. Zircon comes in blue, green, and autumn colors such as cinnamon, sherry, yellow, orange, and red. There are also colorless zircons and cat’s-eye zircons.
You can find many colors of zircon—blue, green, brown, yellow, orange, and red. The colorless zircon is one of the most brilliant non-diamond gems!
Zircon found in Australia is the oldest mineral on earth: It is 4.4 billion years old!
Besides blue, zircon comes in several natural colors. These zircons from Sri Lanka are “untreated,” which means no heat was used to bring out their colors. - Alan Jobbins
what's in a name?
Zircon is possibly from zarkun, the Arabic word for “cinnabar,” a reddish-colored mineral. Or it could be from the Persian word zargun, meaning “gold-colored.”
