Zircon is a natural gemstone known for its remarkable brilliance and high refractive index, making it one of the most sparkly gemstones. Yellow zircon, in particular, derives its color from traces of uranium in its crystal structure. Interestingly, zircon is one of the oldest minerals on Earth, with some specimens dating back over 4 billion years. Despite its beauty, zircon is often confused with cubic zirconia, a synthetic diamond simulant, but zircon is a genuine and valuable gemstone prized for its natural allure and unique characteristics.
