Zircon is a colorful gem with high refraction and fire that’s unfairly confused with cubic zirconia.
Colorless zircon is known for its brilliance and flashes of multicolored light, called fire. These zircon properties are close enough to the properties of diamond to account for centuries of confusion between the two gems.
Zircon occurs in an array of colors. Its varied palette of yellow, green, red, reddish brown, and blue hues makes it a favorite among collectors as well as informed consumers.
Zircon is a birthstone for the month of December, along with turquoise and tanzanite.
WHY WE LOVE THIS GEMSTONE
With radioactive trace elements that tick off time, zircon is a geological clock that tells us about the early earth.
BRILLIANCE AND FIRE
Zircon has very high luster, refractive indices, and dispersion, giving it lots of brilliance and rainbow flashes of fire.
Zircon’s pronounced double refraction means you can see twice as many facets and twice as much fire.
Zircon found in Australia is the oldest mineral on earth: 4.4 billion years old.
Zircon sometimes contains traces of uranium, irradiating itself and changing its properties.
Colorless zircon is called “Matara” zircon after a city in Sri Lanka near where it is mined.
Among consumers, blue is the most popular color of zircon.
