Zircon is the oldest mineral on earth, dating back more than 4.4 billion years. Found in the earth’s crust, it’s common in most sands and sedimentary deposits, as well as metamorphic rocks and crystallized magma.
Due to its chemical makeup, zircon has survived ages of geologic events like erosion and pressure shifts – recording these changes like a time capsule. Zircon contains the radioactive element uranium, which changes the stone’s chemical structure and color over time, giving us important clues about the formation of our planet.
During the Middle Ages, people believed that zircon could induce sound sleep, ward off evil and bring prosperity and wisdom.
Blue zircon, in particular, was popular during Victorian times, and frequently adorned English estate jewelry from the 1880s. Zircon with a cloudy or smoky appearance was also popular in mourning jewelry.
In the 1920s, heat treatment became customary practice to enhance the color of zircon gems for jewelry. Zircon has also been used in the decorative ceramics industry.
Today, zircon is considered a grounding stone that increases confidence and compassion. It is said it can bring visions into reality and provide the guidance needed to achieve goals.
While zircon is popular among gem collectors for its range of colors, consumers seem most enamored with the blue variety, and otherwise confused about the history and possibility of this expansive gem.
