With its high brilliance, Zircon shines brightly among gems and blue is the most popular colour. In fact, so brilliant and fiery is Blue Zircon, it rivals the far more costly blue diamond. An enchanting shade of sea blue, this exceptional jewel is often used to mark December births. Zircon is also available in green, yellow, brown, colourless and red. It should not be confused with the man-made cubic zirconia, a common diamond simulant.
The oldest Zircon is known to be around 4.4 billion years old from Western Australia, the name is thought to have come from the Persian word ‘Zargun’, which means- gold coloured.
