Zircon’s name is either derived from the Arabic word zarkun, meaning red, or a combination of the ancient Persian words zar, meaning gold and gun, meaning color. Despite this name, zircon actually occurs in a myriad of colors.

Zircon’s brilliant luster, fire and bright hues makes it an enjoyable addition to any jewelry collection.

Although zircon’s existence predates cubic zirconia by centuries, zircon is often unfairly confused with cubic zirconia. Cubic zirconia is a cheap, man-made diamond substitute that resembles colorless zircon and has a similar sounding name. While zircon may also be used as an excellent diamond substitute, it is valuable in its own right.

The fire in zircon, called dispersion, is caused by light entering the gemstone and separating into a prism of rainbow colors. Possessing dispersion approaching that of diamond, the brilliance of zircon is second to none. The zircon cut, a variation of the round brilliant cut that adds eight extra facets to the pavilion, was designed to take advantage of these properties.

An interesting characteristic of zircon is that its birefringence (doubly refraction, meaning that light splits into two rays as it passes through the gem) is great enough to producing visible doubling of the back facets in larger stones. Zircon also has an adamantine (diamond-like) luster, lending further credence to its suitability as a diamond substitute.

Zircon remains unscathed while other rocks and minerals melt and reform under the tremendous heat and pressure of continental shifts, mountain-building and violent asteroid impacts. Once only considered a diamond alternative, zircon is in fact incredibly ancient. A tiny fragment of zircon discovered in Western Australia is the oldest known object on earth at 4.4 billion years old (the Earth formed less than 150 million years earlier). Diamonds in comparison are quite young, a mere one billion to 3.3 billion years old.

Cambodia is the world’s premiere source for gorgeous blue zircon. Remote, pristine and stunningly beautiful, Ratanakiri province is the major center for Cambodian zircon, yielding most of the world’s finest blue zircon. Ratanakiri literally means “gemstone mountain.”

Traditionally mining took place near Bo Kheo, some 20 miles from the provincial seat of Ban Lung, but now new areas have been opened. South of Ban Lung, a mining camp exists in the forest, where workers toil to extract Ratanakiri zircon from narrow mine shafts that tap into an alluvial layer about 15 feet below the surface. The author (RWH) visited these remote mines in 2001, finding the work still undertaken by ancient hand methods. Witnessing this gives one a real appreciation of how much work goes into unearthing these wonderful gems.
