Blue zircon is a popular gemstone that has been used for nearly 2000 years in various cultures. It’s known for its beautiful blue color and high refractive index, which gives it a brilliant sparkle. Despite its name, blue zircon is not synthetic and is actually the most valuable of all zircon varieties. It’s often used as a more affordable substitute for blue diamond or sapphire in jewelry. However, it’s important to note that zircon is sensitive to knocks and pressure, so it should be handled with care.
