ABOUT ZIRCON

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.

BIRTHSTONES &
ANNIVERSARIES

Zircon is a birthstone for the month of December, along with turquoise and tanzanite.

 


WHY WE LOVE THIS GEMSTONE

GEOLOGICAL CLOCK

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.

DOUBLE-DOUBLE

Zircon’s pronounced double refraction means you can see twice as many facets and twice as much fire.

4.4 BILLION

Zircon found in Australia is the oldest mineral on earth: 4.4 billion years old.

METAMICTIZATION

Zircon sometimes contains traces of uranium, irradiating itself and changing its properties.

MATARA

Colorless zircon is called “Matara” zircon after a city in Sri Lanka near where it is mined.
