Not to be confused with lab grown "cubic zirconia," zircon is the earliest forming natural gemstone on Earth, believed to have formed 4.4 billion years ago. The stone comes in a variety of colors including golden brown, green, white, blue, and pink. Blue zircon is one of December's three birthstones.
Zircon possesses two unique gemological qualities most gems do not: it has a high birefringence, and it is metamict. Zircon's "high birefringence" directly contributes to how much the stone sparkles; it also gives a visually blurring "doubling" effect that can be observed when looking into the stone. "Metamict" is a term that refers to when a crystal's natural inherent radioactivity causes damage to its own atomic structure over time. The radioactivity of zircon is too faint to have any effect on humans (even with constant everyday wear over one's life), and damage is believed to occur over many millennia.
Zircon ranks 6 to 7.5 on the Mohs hardness scale; green and golden-brown stones are on the softer end of the range (due to being earlier forming material with more time for radioactive change), and blue, pink, and white stones are on the harder end of the range. While zircon is generally regarded durable material, we advise to remove rings when working with your hands to avoid unnecessary wear. It is safe to clean zircon jewelry with chemical jewelry cleaner unless otherwise noted on the label.
