Zircon is a natural gemstone that is a favorite of gem dealers and collectors, but it is not well known in the retail jewelry market. Indeed, some consumers confuse it with cubic zirconia, a cheap synthetic sold as a diamond simulant.
It is valued especially for its high refractive index and excellent fire. In fact zircon has a higher refractive index than sapphire, ruby, spinel or tanzanite. Zircon also has impressive fire, with a dispersion rating nearly as high as diamond. Found in a range of colors, including blue, red, pink, orange, honey, green and white, it makes very attractive jewelry indeed.
Gemologically, it is a zirconium silicate by chemical composition, with a hardness of 7.5 on the Mohs scale. It is suitable for all kinds of jewelry, though protective settings are recommended for rings.
Zircon is ubiquitous in the crust of Earth. It occurs as a common accessory mineral in igneous rocks (as primary crystallization products), in metamorphic rocks and as detrital grains in sedimentary rocks.
