Zircon is a naturally occurring zirconium silicate gemstone admired for its exceptional brilliance, high refractive index, and strong fire, which can rival that of diamond. Found in a wide spectrum of colors—including blue, red, brown, yellow, and rare green—zircon often displays striking clarity and luster when well cut. Although it is relatively durable at 6.5–7.5 on the Mohs scale, it can be brittle and should be worn with care. Formed in igneous and metamorphic environments and known as one of Earth’s oldest minerals, zircon is sourced from regions such as Sri Lanka, Cambodia, and Australia, where its natural beauty continues to make it a popular choice among gem enthusiasts and collectors.
