Despite the gemstone name’s similarity with a popular diamond stimulant, zircons are a specific category of gemstones and are considered to be one of the oldest (if not the oldest) gemstones in the world. With certain zircons found in parts of Australia being dated billions of years into the past. Zircons are known for their high reflectivity and valued for their acceptable level of hardness: 6 – 7.5 in the Mohs scale. Zircon comes in a range of colours, from yellow to blue, from black to white. With blue zircons being among the more popular choices when it comes to jewellery. Zircon over the years has struggled with establishing its identity, as it is often confused with diamond simulant, however, zircon in recent times have started to make a comeback, the silicate mineral, with the popular yellow-gold variants among the most sought after type. Zircons are found in a number of countries across the world.
